-		  GNU LESSER GENERAL PUBLIC LICENSE
-		       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-		  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of

-Copyright 1994, 1995, 1996, 1999, 2000, 2001, 2002 Free Software
-Foundation, Inc.
-

-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
-   These are generic installation instructions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  (Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.)
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You only need
-`configure.ac' if you want to change it or regenerate `configure' using
-a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes awhile.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  Run `./configure --help'
-for details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   If you have to use a `make' that does not support the `VPATH'
-variable, you have to compile the package for one architecture at a
-time in the source code directory.  After you have installed the
-package for one architecture, use `make distclean' before reconfiguring
-for another architecture.
-
-Installation Names
-==================
-
-   By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the `--target=TYPE' option to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-   Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-will cause the specified gcc to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-`configure' Invocation
-======================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
-     Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

-<title>Setting Up Distributed Builds</title>
-
-<para>Nix supports distributed builds: a local Nix installation can
-forward Nix builds to other machines over the network.  This allows
-multiple builds to be performed in parallel (thus improving
-performance) and allows Nix to perform multi-platform builds in a
-semi-transparent way.  For instance, if you perform a build for a
-<literal>powerpc-darwin</literal> on an <literal>i686-linux</literal>
-machine, Nix can automatically forward the build to a
-<literal>powerpc-darwin</literal> machine, if available.</para>
-
-<para>You can enable distributed builds by setting the environment
-variable <envar>NIX_BUILD_HOOK</envar> to point to a program that Nix
-will call whenever it wants to build a derivation.  The build hook
-(typically a shell or Perl script) can decline the build, in which Nix
-will perform it in the usual way if possible, or it can accept it, in
-which case it is responsible for somehow getting the inputs of the
-build to another machine, doing the build there, and getting the
-results back.  The details of the build hook protocol are described in
-the documentation of the <link
-linkend="envar-build-hook"><envar>NIX_BUILD_HOOK</envar>
-variable</link>.</para>

-<example xml:id='ex-remote-systems'><title>Remote machine configuration:
-<filename>remote-systems.conf</filename></title>

-</programlisting>
-</example>
-
-<para>Nix ships with a build hook that should be suitable for most
-purposes.  It uses <command>ssh</command> and
-<command>nix-copy-closure</command> to copy the build inputs and
-outputs and perform the remote build.  To use it, you should set
-<envar>NIX_BUILD_HOOK</envar> to
-<filename><replaceable>prefix</replaceable>/libexec/nix/build-remote.pl</filename>.
-You should also define a list of available build machines and point
-the environment variable <envar>NIX_REMOTE_SYSTEMS</envar> to it.  An
-example configuration is shown in <xref linkend='ex-remote-systems'
-/>.  Each line in the file specifies a machine, with the following
-bits of information:
-
-<orderedlist>
-  
-  <listitem><para>The name of the remote machine, with optionally the
-  user under which the remote build should be performed.  This is
-  actually passed as an argument to <command>ssh</command>, so it can
-  be an alias defined in your
-  <filename>~/.ssh/config</filename>.</para></listitem>
-
-  <listitem><para>A comma-separated list of Nix platform type
-  identifiers, such as <literal>powerpc-darwin</literal>.  It is
-  possible for a machine to support multiple platform types, e.g.,
-  <literal>i686-linux,x86_64-linux</literal>.</para></listitem>
-
-  <listitem><para>The SSH private key to be used to log in to the
-  remote machine.  Since builds should be non-interactive, this key
-  should not have a passphrase!</para></listitem>
-
-  <listitem><para>The maximum number of builds that
-  <filename>build-remote.pl</filename> will execute in parallel on the
-  machine.  Typically this should be equal to the number of CPU cores.
-  For instance, the machine <literal>itchy</literal> in the example
-  will execute up to 8 builds in parallel.</para></listitem>
-
-  <listitem><para>The “speed factor”, indicating the relative speed of
-  the machine.  If there are multiple machines of the right type, Nix
-  will prefer the fastest, taking load into account.</para></listitem>
-
-  <listitem><para>A comma-separated list of <emphasis>supported
-  features</emphasis>.  If a derivation has the
-  <varname>requiredSystemFeatures</varname> attribute, then
-  <filename>build-remote.pl</filename> will only perform the
-  derivation on a machine that has the specified features.  For
-  instance, the attribute
-  
-<programlisting>
-requiredSystemFeatures = [ "kvm" ];  
-</programlisting>
-
-  will cause the build to be performed on a machine that has the
-  <literal>kvm</literal> feature (i.e., <literal>scratchy</literal> in
-  the example above).</para></listitem>
-
-  <listitem><para>A comma-separated list of <emphasis>mandatory
-  features</emphasis>.  A machine will only be used to build a
-  derivation if all of the machine’s mandatory features appear in the
-  derivation’s <varname>requiredSystemFeatures</varname> attribute.
-  Thus, in the example, the machine <literal>poochie</literal> will
-  only do derivations that have

-
-</orderedlist>
-
-You should also set up the environment variable

-<filename>/var/run/nix/current-load</filename>) that
-<filename>build-remote.pl</filename> uses to remember how many builds
-it is currently executing remotely.  It doesn't look at the actual

-
-      <para>This function allows you to copy sources into the Nix
-      store while filtering certain files.  For instance, suppose that
-      you want to use the directory <filename>source-dir</filename> as
-      an input to a Nix expression, e.g.
-
-<programlisting>
-stdenv.mkDerivation {
-  ...
-  src = ./source-dir;
-}
-</programlisting>
-
-      However, if <filename>source-dir</filename> is a Subversion
-      working copy, then all those annoying <filename>.svn</filename>
-      subdirectories will also be copied to the store.  Worse, the
-      contents of those directories may change a lot, causing lots of
-      spurious rebuilds.  With <function>filterSource</function> you
-      can filter out the <filename>.svn</filename> directories:
-
-<programlisting>
-  src = builtins.filterSource
-    (path: type: type != "directory" || baseNameOf path != ".svn")
-    ./source-dir;
-</programlisting>
-
-      </para>
-
-      <para>Thus, the first argument <replaceable>e1</replaceable>
-      must be a predicate function that is called for each regular
-      file, directory or symlink in the source tree
-      <replaceable>e2</replaceable>.  If the function returns
-      <literal>true</literal>, the file is copied to the Nix store,
-      otherwise it is omitted.  The function is called with two
-      arguments.  The first is the full path of the file.  The second
-      is a string that identifies the type of the file, which is
-      either <literal>"regular"</literal>,
-      <literal>"directory"</literal>, <literal>"symlink"</literal> or
-      <literal>"unknown"</literal> (for other kinds of files such as
-      device nodes or fifos — but note that those cannot be copied to
-      the Nix store, so if the predicate returns
-      <literal>true</literal> for them, the copy will fail).</para>

-
-  <para>Normally, the Nix store directory (typically
-  <filename>/nix/store</filename>) is not allowed to contain any
-  symlink components.  This is to prevent “impure” builds.  Builders
-  sometimes “canonicalise” paths by resolving all symlink components.
-  Thus, builds on different machines (with
-  <filename>/nix/store</filename> resolving to different locations)
-  could yield different results.  This is generally not a problem,
-  except when builds are deployed to machines where
-  <filename>/nix/store</filename> resolves differently.  If you are
-  sure that you’re not going to do that, you can set
-  <envar>NIX_IGNORE_SYMLINK_STORE</envar> to <envar>1</envar>.</para>
-
-  <para>Note that if you’re symlinking the Nix store so that you can
-  put it on another file system than the root file system, on Linux
-  you’re better off using <literal>bind</literal> mount points, e.g.,

-
-  <glossdef><para>The assumption that equal Nix derivations when run

-<section><title>Security</title>
-
-<para>Nix has two basic security models.  First, it can be used in
-“single-user mode”, which is similar to what most other package
-management tools do: there is a single user (typically <systemitem
-class="username">root</systemitem>) who performs all package
-management operations.  All other users can then use the installed
-packages, but they cannot perform package management operations
-themselves.</para>
-
-<para>Alternatively, you can configure Nix in “multi-user mode”.  In
-this model, all users can perform package management operations — for
-instance, every user can install software without requiring root
-privileges.  Nix ensures that this is secure.  For instance, it’s not
-possible for one user to overwrite a package used by another user with
-a Trojan horse.</para>
-
-
-<section><title>Single-user mode</title>
-  
-<para>In single-user mode, all Nix operations that access the database
-in <filename><replaceable>prefix</replaceable>/var/nix/db</filename>
-or modify the Nix store in
-<filename><replaceable>prefix</replaceable>/store</filename> must be
-performed under the user ID that owns those directories.  This is
-typically <systemitem class="username">root</systemitem>.  (If you
-install from RPM packages, that’s in fact the default ownership.)
-However, on single-user machines, it is often convenient to
-<command>chown</command> those directories to your normal user account
-so that you don’t have to <command>su</command> to <systemitem
-class="username">root</systemitem> all the time.</para>
-
-</section>
-
-
-<section xml:id="ssec-multi-user"><title>Multi-user mode</title>
-
-<para>To allow a Nix store to be shared safely among multiple users,
-it is important that users are not able to run builders that modify
-the Nix store or database in arbitrary ways, or that interfere with
-builds started by other users.  If they could do so, they could
-install a Trojan horse in some package and compromise the accounts of
-other users.</para>
-
-<para>To prevent this, the Nix store and database are owned by some
-privileged user (usually <literal>root</literal>) and builders are
-executed under special user accounts (usually named
-<literal>nixbld1</literal>, <literal>nixbld2</literal>, etc.).  When a
-unprivileged user runs a Nix command, actions that operate on the Nix
-store (such as builds) are forwarded to a <emphasis>Nix
-daemon</emphasis> running under the owner of the Nix store/database
-that performs the operation.</para>
-
-<note><para>Multi-user mode has one important limitation: only
-<systemitem class="username">root</systemitem> can run <command
-linkend="sec-nix-pull">nix-pull</command> to register the availability
-of pre-built binaries.  However, those registrations are shared by all
-users, so they still get the benefit from <command>nix-pull</command>s
-done by <systemitem class="username">root</systemitem>.</para></note>
-
-
-<section><title>Setting up the build users</title>
-
-<para>The <emphasis>build users</emphasis> are the special UIDs under
-which builds are performed.  They should all be members of the
-<emphasis>build users group</emphasis> (usually called
-<literal>nixbld</literal>).  This group should have no other members.
-The build users should not be members of any other group.</para>
-
-<para>Here is a typical <filename>/etc/group</filename> definition of
-the build users group with 10 build users:
-
-<programlisting>
-nixbld:!:30000:nixbld1,nixbld2,nixbld3,nixbld4,nixbld5,nixbld6,nixbld7,nixbld8,nixbld9,nixbld10
-</programlisting>
-
-In this example the <literal>nixbld</literal> group has UID 30000, but
-of course it can be anything that doesn’t collide with an existing
-group.</para>
-
-<para>Here is the corresponding part of
-<filename>/etc/passwd</filename>:
-
-<programlisting>
-nixbld1:x:30001:65534:Nix build user 1:/var/empty:/noshell
-nixbld2:x:30002:65534:Nix build user 2:/var/empty:/noshell
-nixbld3:x:30003:65534:Nix build user 3:/var/empty:/noshell
-...
-nixbld10:x:30010:65534:Nix build user 10:/var/empty:/noshell
-</programlisting>
-
-The home directory of the build users should not exist or should be an
-empty directory to which they do not have write access.</para>
-
-<para>The build users should have write access to the Nix store, but
-they should not have the right to delete files.  Thus the Nix store’s
-group should be the build users group, and it should have the sticky
-bit turned on (like <filename>/tmp</filename>):
-
-<screen>
-$ chown root.nixbld /nix/store
-$ chmod 1775 /nix/store
-</screen>
-
-</para>
-
-<para>Finally, you should tell Nix to use the build users by
-specifying the build users group in the <link
-linkend="conf-build-users-group"><literal>build-users-group</literal>
-option</link> in the <link linkend="sec-conf-file">Nix configuration
-file</link> (usually <literal>/etc/nix/nix.conf</literal>):
-
-<programlisting>
-build-users-group = nixbld
-</programlisting>
-
-</para>
-
-</section>
-
-
-<section><title>Running the daemon</title>
-
-<para>The <link linkend="sec-nix-daemon">Nix daemon</link> should be
-started as follows (as <literal>root</literal>):
-
-<screen>
-$ nix-daemon</screen>
-
-You’ll want to put that line somewhere in your system’s boot

-
-<para>To let unprivileged users use the daemon, they should set the
-<link linkend="envar-remote"><envar>NIX_REMOTE</envar> environment
-variable</link> to <literal>daemon</literal>.  So you should put a
-line like
-
-<programlisting>
-export NIX_REMOTE=daemon</programlisting>
-
-into the users’ login scripts.</para>
-
-</section>
-
-
-<section><title>Restricting access</title>
-
-<para>To limit which users can perform Nix operations, you can use the
-permissions on the directory
-<filename>/nix/var/nix/daemon-socket</filename>.  For instance, if you
-want to restrict the use of Nix to the members of a group called
-<literal>nix-users</literal>, do
-
-<screen>
-$ chgrp nix-users /nix/var/nix/daemon-socket
-$ chmod ug=rwx,o= /nix/var/nix/daemon-socket
-</screen>
-
-This way, users who are not in the <literal>nix-users</literal> group
-cannot connect to the Unix domain socket
-<filename>/nix/var/nix/daemon-socket/socket</filename>, so they cannot
-perform Nix operations.</para>

-
-</section> <!-- end of security -->
-
-
-<section><title>Using Nix</title>
-
-<para>To use Nix, some environment variables should be set.  In
-particular, <envar>PATH</envar> should contain the directories
-<filename><replaceable>prefix</replaceable>/bin</filename> and
-<filename>~/.nix-profile/bin</filename>.  The first directory contains
-the Nix tools themselves, while <filename>~/.nix-profile</filename> is
-a symbolic link to the current <emphasis>user environment</emphasis>
-(an automatically generated package consisting of symlinks to
-installed packages).  The simplest way to set the required environment
-variables is to include the file
-<filename><replaceable>prefix</replaceable>/etc/profile.d/nix.sh</filename>
-in your <filename>~/.profile</filename> (or similar), like this:</para>
-
-<screen>
-source <replaceable>prefix</replaceable>/etc/profile.d/nix.sh</screen>

-<title>Introduction</title>
-
-
-<section><title>About Nix</title>
-
-<para>Nix is a <emphasis>purely functional package manager</emphasis>.
-This means that it treats packages like values in purely functional
-programming languages such as Haskell — they are built by functions
-that don’t have side-effects, and they never change after they have
-been built.  Nix stores packages in the <emphasis>Nix
-store</emphasis>, usually the directory
-<filename>/nix/store</filename>, where each package has its own unique
-subdirectory such as
-
-<programlisting>
-/nix/store/nlc4z5y1hm8w9s8vm6m1f5hy962xjmp5-firefox-12.0
-</programlisting>
-
-where <literal>nlc4z5…</literal> is a unique identifier for the
-package that captures all its dependencies (it’s a cryptographic hash
-of the package’s build dependency graph).  This enables many powerful
-features.</para>
-
-
-<simplesect><title>Multiple versions</title>
-
-<para>You can have multiple versions or variants of a package
-installed at the same time.  This is especially important when
-different applications have dependencies on different versions of the
-same package — it prevents the “DLL hell”.  Because of the hashing
-scheme, different versions of a package end up in different paths in
-the Nix store, so they don’t interfere with each other.</para>
-
-<para>An important consequence is that operations like upgrading or
-uninstalling an application cannot break other applications, since
-these operations never “destructively” update or delete files that are
-used by other packages.</para>
-
-</simplesect>
-
-
-<simplesect><title>Complete dependencies</title>
-
-<para>Nix helps you make sure that package dependency specifications
-are complete.  In general, when you’re making a package for a package
-management system like RPM, you have to specify for each package what
-its dependencies are, but there are no guarantees that this
-specification is complete.  If you forget a dependency, then the
-package will build and work correctly on <emphasis>your</emphasis>
-machine if you have the dependency installed, but not on the end
-user's machine if it's not there.</para>
-
-<para>Since Nix on the other hand doesn’t install packages in “global”
-locations like <filename>/usr/bin</filename> but in package-specific
-directories, the risk of incomplete dependencies is greatly reduced.
-This is because tools such as compilers don’t search in per-packages
-directories such as
-<filename>/nix/store/5lbfaxb722zp…-openssl-0.9.8d/include</filename>,
-so if a package builds correctly on your system, this is because you
-specified the dependency explicitly.</para>
-
-<para>Runtime dependencies are found by scanning binaries for the hash
-parts of Nix store paths (such as <literal>r8vvq9kq…</literal>).  This
-sounds risky, but it works extremely well.</para>
-
-</simplesect>
-
-
-<simplesect><title>Multi-user support</title>
-
-<para>Nix has multi-user support.  This means that non-privileged
-users can securely install software.  Each user can have a different
-<emphasis>profile</emphasis>, a set of packages in the Nix store that
-appear in the user’s <envar>PATH</envar>.  If a user installs a
-package that another user has already installed previously, the
-package won’t be built or downloaded a second time.  At the same time,
-it is not possible for one user to inject a Trojan horse into a
-package that might be used by another user.</para>

-</simplesect>
-
-
-<simplesect><title>Atomic upgrades and rollbacks</title>
-
-<para>Since package management operations never overwrite packages in
-the Nix store but just add new versions in different paths, they are
-<emphasis>atomic</emphasis>.  So during a package upgrade, there is no
-time window in which the package has some files from the old version
-and some files from the new version — which would be bad because a
-program might well crash if it’s started during that period.</para>
-
-<para>And since package aren’t overwritten, the old versions are still
-there after an upgrade.  This means that you can <emphasis>roll
-back</emphasis> to the old version:</para>
-
-<screen>
-$ nix-env --upgrade <replaceable>some-packages</replaceable>
-$ nix-env --rollback
-</screen>
-
-</simplesect>
-
-
-<simplesect><title>Garbage collection</title>
-
-<para>When you uninstall a package like this…
-
-<screen>
-$ nix-env --uninstall firefox
-</screen>
-
-the package isn’t deleted from the system right away (after all, you
-might want to do a rollback, or it might be in the profiles of other
-users).  Instead, unused packages can be deleted safely by running the
-<emphasis>garbage collector</emphasis>:
-
-<screen>
-$ nix-collect-garbage
-</screen>
-
-This deletes all packages that aren’t in use by any user profile or by
-a currently running program.</para>
-
-</simplesect>
-
-
-<simplesect><title>Functional package language</title>
-
-<para>Packages are built from <emphasis>Nix expressions</emphasis>,
-which is a simple functional language.  A Nix expression describes
-everything that goes into a package build action (a “derivation”):
-other packages, sources, the build script, environment variables for
-the build script, etc.  Nix tries very hard to ensure that Nix
-expressions are <emphasis>deterministic</emphasis>: building a Nix
-expression twice should yield the same result.</para>
-
-<para>Because it’s a functional language, it’s easy to support
-building variants of a package: turn the Nix expression into a
-function and call it any number of times with the appropriate
-arguments.  Due to the hashing scheme, variants don’t conflict with
-each other in the Nix store.</para>
-
-</simplesect>
-
-
-<simplesect><title>Transparent source/binary deployment</title>
-
-<para>Nix expressions generally describe how to build a package from
-source, so an installation action like
-
-<screen>
-$ nix-env --install firefox
-</screen>
-
-<emphasis>could</emphasis> cause quite a bit of build activity, as not
-only Firefox but also all its dependencies (all the way up to the C
-library and the compiler) would have to built, at least if they are
-not already in the Nix store.  This is a <emphasis>source deployment
-model</emphasis>.  For most users, building from source is not very
-pleasant as it takes far too long.  However, Nix can automatically
-skip building from source and download a pre-built binary instead if
-it knows about it.  <emphasis>Nix channels</emphasis> provide Nix
-expressions along with pre-built binaries.</para>
-
-<!--

-href="http://www.gentoo.org/">Gentoo</a>) and a binary model (like

-
-</simplesect>
-
-
-<simplesect><title>Binary patching</title>
-
-<para>In addition to downloading binaries automatically if they’re
-available, Nix can download binary deltas that patch an existing
-package in the Nix store into a new version.  This speeds up
-upgrades.</para>
-
-</simplesect>
-
-
-<simplesect><title>Nix Packages collection</title>
-
-<para>We provide a large set of Nix expressions containing hundreds of
-existing Unix packages, the <emphasis>Nix Packages
-collection</emphasis> (Nixpkgs).</para>
-
-</simplesect>
-
-
-<simplesect><title>Service deployment</title>
-
-<para>Nix can be used not only for rolling out packages, but also
-complete <emphasis>configurations</emphasis> of services.  This is
-done by treating all the static bits of a service (such as software
-packages, configuration files, control scripts, static web pages,
-etc.) as “packages” that can be built by Nix expressions.  As a
-result, all the features above apply to services as well: for
-instance, you can roll back a web server configuration if a
-configuration change turns out to be undesirable, you can easily have
-multiple instances of a service (e.g., a test and production server),
-and because the whole service is built in a purely functional way from
-a Nix expression, it is repeatable so you can easily reproduce the
-service on another machine.</para>

-
-<para>NixOS is a Linux distribution based on Nix.  It uses Nix not
-just for package management but also to manage the system
-configuration (e.g., to build configuration files in
-<filename>/etc</filename>).  This means, among other things, that it’s
-possible to easily roll back the entire configuration of the system to
-an earlier state.  Also, users can install software without root

-<para>Nix was originally developed at the <link
-xlink:href="http://www.cs.uu.nl/">Department of Information and
-Computing Sciences</link>, Utrecht University by the <link
-xlink:href="http://www.cs.uu.nl/wiki/Trace/WebHome">TraCE
-project</link> (2003-2008).  The project was funded by the Software
-Engineering Research Program <link
-xlink:href="http://www.jacquard.nl/">Jacquard</link> to improve the
-support for variability in software systems.  Further funding was
-provided by the NIRICT LaQuSo Build Farm project.  Development is

-<section><title>About this manual</title>
-
-<para>This manual tells you how to install and use Nix and how to
-write Nix expressions for software not already in the Nix Packages
-collection.  It also discusses some advanced topics, such as setting
-up distributed multi-platform building.</para>

-If the build succeeds, it places a symlink to the result in the

-If there are multiple Nix expressions, or the Nix expressions evaluate
-to multiple derivations, multiple sequentially numbered symlinks are
-created (<filename>result</filename>, <filename>result-2</filename>,
-and so on).</para>

-<para>The install operation creates a new user environment, based on
-the current generation of the active profile, to which a set of store
-paths described by <replaceable>args</replaceable> is added.  The
-arguments <replaceable>args</replaceable> map to store paths in a
-number of possible ways:
-
-<itemizedlist>
-
-  <listitem><para>By default, <replaceable>args</replaceable> is a set
-  of derivation names denoting derivations in the active Nix
-  expression.  These are realised, and the resulting output paths are
-  installed.  Currently installed derivations with a name equal to the
-  name of a derivation being added are removed unless the option
-  <option>--preserve-installed</option> is
-  specified.</para>
-
-  <para>If there are multiple derivations matching a name in
-  <replaceable>args</replaceable> that have the same name (e.g.,
-  <literal>gcc-3.3.6</literal> and <literal>gcc-4.1.1</literal>), then
-  the derivation with the highest <emphasis>priority</emphasis> is
-  used.  A derivation can define a priority by declaring the
-  <varname>meta.priority</varname> attribute.  This attribute should
-  be a number, with a higher value denoting a lower priority.  The
-  default priority is <literal>0</literal>.</para>
-
-  <para>If there are multiple matching derivations with the same
-  priority, then the derivation with the highest version will be
-  installed.</para>
-
-  <para>You can force the installation of multiple derivations with
-  the same name by being specific about the versions.  For instance,
-  <literal>nix-env -i gcc-3.3.6 gcc-4.1.1</literal> will install both
-  version of GCC (and will probably cause a user environment
-  conflict!).</para></listitem>
-
-  <listitem><para>If <link
-  linkend='opt-attr'><option>--attr</option></link>
-  (<option>-A</option>) is specified, the arguments are
-  <emphasis>attribute paths</emphasis> that select attributes from the
-  top-level Nix expression.  This is faster than using derivation
-  names and unambiguous.  To find out the attribute paths of available
-  packages, use <literal>nix-env -qaP '*'</literal>.</para></listitem>
-
-  <listitem><para>If <option>--from-profile</option>
-  <replaceable>path</replaceable> is given,
-  <replaceable>args</replaceable> is a set of names denoting installed

-<itemizedlist>
-
-  <listitem><para><varname>priority</varname> can be changed to

-  the <varname>meta.priority</varname> attribute of derivations to
-  resolve filename collisions between packages.  Lower priority values
-  denote a higher priority.  For instance, the GCC wrapper package and
-  the Binutils package in Nixpkgs both have a file
-  <filename>bin/ld</filename>, so previously if you tried to install
-  both you would get a collision.  Now, on the other hand, the GCC
-  wrapper declares a higher priority than Binutils, so the former’s

-  environment.</para></listitem>

-<para>The hash is computed over a <emphasis>serialisation</emphasis>

-The dump is in the <emphasis>NAR format</emphasis> produced by <link

-<para>This command is just a convenience for Nix expression writers.

-
-    <para>In conjunction with <option>--add-root</option>, this option

-    garbage-collected unless the symlink is removed.</para>
-
-    <para>The <option>--indirect</option> flag causes a uniquely named
-    symlink to <replaceable>path</replaceable> to be stored in

-    Thus, when <filename>/home/eelco/bla/result</filename> is removed,
-    the GC root in the <filename>auto</filename> directory becomes a

-
-    <warning><para>Note that it is not possible to move or rename

-<para>The operation <option>--dump</option> produces a NAR (Nix

-at <replaceable>path</replaceable>.  The archive is written to
-standard output.</para>
-
-<para>A NAR archive is like a TAR or Zip archive, but it contains only
-the information that Nix considers important.  For instance,
-timestamps are elided because all files in the Nix store have their
-timestamp set to 0 anyway.  Likewise, all permissions are left out
-except for the execute bit, because all files in the Nix store have
-644 or 755 permission.</para>
-
-<para>Also, a NAR archive is <emphasis>canonical</emphasis>, meaning
-that “equal” paths always produce the same NAR archive.  For instance,
-directory entries are always sorted so that the actual on-disk order
-doesn’t influence the result.  This means that the cryptographic hash
-of a NAR dump of a path is usable as a fingerprint of the contents of
-the path.  Indeed, the hashes of store paths stored in Nix’s database
-(see <link linkend="refsec-nix-store-query"><literal>nix-store -q
---hash</literal></link>) are SHA-256 hashes of the NAR dump of each
-store path.</para>

-links, but not other types of files (such as device nodes).</para>

-
-  <listitem><para>This option is accepted by
-  <command>nix-env</command>, <command>nix-instantiate</command> and
-  <command>nix-build</command>.  When evaluating Nix expressions, the
-  expression evaluator will automatically try to call functions that
-  it encounters.  It can automatically call functions for which every
-  argument has a <link linkend='ss-functions'>default value</link>
-  (e.g., <literal>{ <replaceable>argName</replaceable> ?
-  <replaceable>defaultValue</replaceable> }:
-  <replaceable>...</replaceable></literal>).  With
-  <option>--arg</option>, you can also call functions that have
-  arguments without a default value (or override a default value).
-  That is, if the evaluator encounters a function with an argument
-  named <replaceable>name</replaceable>, it will call it with value
-  <replaceable>value</replaceable>.</para>
-
-  <para>For instance, the file
-  <literal>pkgs/top-level/all-packages.nix</literal> in Nixpkgs is
-  actually a function:
-
-<programlisting>
-{ # The system (e.g., `i686-linux') for which to build the packages.
-  system ? builtins.currentSystem
-  <replaceable>...</replaceable>
-}: <replaceable>...</replaceable></programlisting>
-
-  So if you call this Nix expression (e.g., when you do
-  <literal>nix-env -i <replaceable>pkgname</replaceable></literal>),
-  the function will be called automatically using the value <link
-  linkend='builtin-currentSystem'><literal>builtins.currentSystem</literal></link>
-  for the <literal>system</literal> argument.  You can override this
-  using <option>--arg</option>, e.g., <literal>nix-env -i
-  <replaceable>pkgname</replaceable> --arg system
-  \"i686-freebsd\"</literal>.  (Note that since the argument is a Nix
-  string literal, you have to escape the quotes.)</para></listitem>

-<title>Package Management</title>
-
-
-<para>This chapter discusses how to do package management with Nix,
-i.e., how to obtain, install, upgrade, and erase packages.  This is
-the “user’s” perspective of the Nix system — people
-who want to <emphasis>create</emphasis> packages should consult
-<xref linkend='chap-writing-nix-expressions' />.</para>
-
-
-<section><title>Basic package management</title>
-
-<para>The main command for package management is <link
-linkend="sec-nix-env"><command>nix-env</command></link>.  You can use
-it to install, upgrade, and erase packages, and to query what
-packages are installed or are available for installation.</para>
-
-<para>In Nix, different users can have different “views”
-on the set of installed applications.  That is, there might be lots of
-applications present on the system (possibly in many different
-versions), but users can have a specific selection of those active —
-where “active” just means that it appears in a directory
-in the user’s <envar>PATH</envar>.  Such a view on the set of
-installed applications is called a <emphasis>user
-environment</emphasis>, which is just a directory tree consisting of
-symlinks to the files of the active applications.  </para>
-
-<para>Components are installed from a set of <emphasis>Nix
-expressions</emphasis> that tell Nix how to build those packages,
-including, if necessary, their dependencies.  There is a collection of
-Nix expressions called the Nix Package collection that contains
-packages ranging from basic development stuff such as GCC and Glibc,
-to end-user applications like Mozilla Firefox.  (Nix is however not
-tied to the Nix Package collection; you could write your own Nix
-expressions based on it, or completely new ones.)  You can download
-the latest version from <link
-xlink:href='http://nixos.org/nixpkgs/download.html' />.</para>
-
-<para>Assuming that you have downloaded and unpacked a release of Nix
-Packages, you can view the set of available packages in the release:
-
-<screen>
-$ nix-env -qaf nixpkgs-<replaceable>version</replaceable> '*'
-ant-blackdown-1.4.2
-aterm-2.2
-bash-3.0
-binutils-2.15
-bison-1.875d
-blackdown-1.4.2
-bzip2-1.0.2
-...</screen>
-
-where <literal>nixpkgs-<replaceable>version</replaceable></literal> is
-where you’ve unpacked the release.  The flag <option>-q</option>
-specifies a query operation; <option>-a</option> means that you want
-to show the “available” (i.e., installable) packages, as opposed to
-the installed packages; and <option>-f</option>
-<filename>nixpkgs-<replaceable>version</replaceable></filename>
-specifies the source of the packages.  The argument
-<literal>'*'</literal> shows all installable packages. (The quotes are
-necessary to prevent shell expansion.)  You can also select specific
-packages by name:
-
-<screen>
-$ nix-env -qaf nixpkgs-<replaceable>version</replaceable> gcc
-gcc-3.4.6
-gcc-4.0.3
-gcc-4.1.1</screen>
-
-</para>
-
-<para>It is also possible to see the <emphasis>status</emphasis> of
-available packages, i.e., whether they are installed into the user
-environment and/or present in the system:
-
-<screen>
-$ nix-env -qasf nixpkgs-<replaceable>version</replaceable> '*'
-...
--PS bash-3.0
---S binutils-2.15
-IPS bison-1.875d
-...</screen>
-
-The first character (<literal>I</literal>) indicates whether the
-package is installed in your current user environment.  The second
-(<literal>P</literal>) indicates whether it is present on your system
-(in which case installing it into your user environment would be a
-very quick operation).  The last one (<literal>S</literal>) indicates
-whether there is a so-called <emphasis>substitute</emphasis> for the
-package, which is Nix’s mechanism for doing binary deployment.  It
-just means that Nix knows that it can fetch a pre-built package from
-somewhere (typically a network server) instead of building it
-locally.</para>
-
-<para>So now that we have a set of Nix expressions we can build the
-packages contained in them.  This is done using <literal>nix-env
--i</literal>.  For instance,
-
-<screen>
-$ nix-env -f nixpkgs-<replaceable>version</replaceable> -i subversion</screen>
-
-will install the package called <literal>subversion</literal> (which
-is, of course, the <link
-xlink:href='http://subversion.tigris.org/'>Subversion version
-management system</link>).</para>
-
-<para>When you do this for the first time, Nix will start building
-Subversion and all its dependencies.  This will take quite a while —
-typically an hour or two on modern machines.  Fortunately, there is a
-faster way (so do a Ctrl-C on that install operation!): you just need
-to tell Nix that pre-built binaries of all those packages are
-available somewhere.  This is done using the
-<command>nix-pull</command> command, which must be supplied with a URL
-containing a <emphasis>manifest</emphasis> describing what binaries
-are available.  This URL should correspond to the Nix Packages release
-that you’re using.  For instance, if you obtained a release from <link
-xlink:href='http://nixos.org/releases/nixpkgs/nixpkgs-0.12pre11712-4lrp7j8x'
-/>, then you should do:
-
-<screen>
-$ nix-pull http://nixos.org/releases/nixpkgs/nixpkgs-0.12pre11712-4lrp7j8x/MANIFEST</screen>
-
-If you then issue the installation command, it should start
-downloading binaries from <systemitem
-class='fqdomainname'>nixos.org</systemitem>, instead of building
-them from source.  This might still take a while since all
-dependencies must be downloaded, but on a reasonably fast connection
-such as a DSL line it’s on the order of a few minutes.</para>
-
-<para>Naturally, packages can also be uninstalled:
-
-<screen>
-$ nix-env -e subversion</screen>
-
-</para>
-
-<para>Upgrading to a new version is just as easy.  If you have a new
-release of Nix Packages, you can do:
-
-<screen>
-$ nix-env -f nixpkgs-<replaceable>version</replaceable> -u subversion</screen>
-
-This will <emphasis>only</emphasis> upgrade Subversion if there is a
-“newer” version in the new set of Nix expressions, as
-defined by some pretty arbitrary rules regarding ordering of version
-numbers (which generally do what you’d expect of them).  To just
-unconditionally replace Subversion with whatever version is in the Nix
-expressions, use <parameter>-i</parameter> instead of
-<parameter>-u</parameter>; <parameter>-i</parameter> will remove
-whatever version is already installed.</para>
-
-<para>You can also upgrade all packages for which there are newer
-versions:
-
-<screen>
-$ nix-env -f nixpkgs-<replaceable>version</replaceable> -u '*'</screen>
-
-</para>
-
-<para>Sometimes it’s useful to be able to ask what
-<command>nix-env</command> would do, without actually doing it.  For
-instance, to find out what packages would be upgraded by
-<literal>nix-env -u '*'</literal>, you can do
-
-<screen>
-$ nix-env ... -u '*' --dry-run
-(dry run; not doing anything)
-upgrading `libxslt-1.1.0' to `libxslt-1.1.10'
-upgrading `graphviz-1.10' to `graphviz-1.12'
-upgrading `coreutils-5.0' to `coreutils-5.2.1'</screen>

-<section xml:id="sec-profiles"><title>Profiles</title>
-
-<para>Profiles and user environments are Nix’s mechanism for
-implementing the ability to allow different users to have different
-configurations, and to do atomic upgrades and rollbacks.  To
-understand how they work, it’s useful to know a bit about how Nix
-works.  In Nix, packages are stored in unique locations in the
-<emphasis>Nix store</emphasis> (typically,
-<filename>/nix/store</filename>).  For instance, a particular version
-of the Subversion package might be stored in a directory
-<filename>/nix/store/dpmvp969yhdqs7lm2r1a3gng7pyq6vy4-subversion-1.1.3/</filename>,
-while another version might be stored in
-<filename>/nix/store/5mq2jcn36ldlmh93yj1n8s9c95pj7c5s-subversion-1.1.2</filename>.
-The long strings prefixed to the directory names are cryptographic
-hashes<footnote><para>160-bit truncations of SHA-256 hashes encoded in
-a base-32 notation, to be precise.</para></footnote> of
-<emphasis>all</emphasis> inputs involved in building the package —
-sources, dependencies, compiler flags, and so on.  So if two
-packages differ in any way, they end up in different locations in
-the file system, so they don’t interfere with each other.  <xref
-linkend='fig-user-environments' /> shows a part of a typical Nix
-store.</para>
-
-<figure xml:id='fig-user-environments'><title>User environments</title>
-  <mediaobject>
-    <imageobject>
-      <imagedata fileref='figures/user-environments.png' format='PNG' />
-    </imageobject>
-  </mediaobject>
-</figure>
-
-<para>Of course, you wouldn’t want to type
-
-<screen>
-$ /nix/store/dpmvp969yhdq...-subversion-1.1.3/bin/svn</screen>
-
-every time you want to run Subversion.  Of course we could set up the
-<envar>PATH</envar> environment variable to include the
-<filename>bin</filename> directory of every package we want to use,
-but this is not very convenient since changing <envar>PATH</envar>
-doesn’t take effect for already existing processes.  The solution Nix
-uses is to create directory trees of symlinks to
-<emphasis>activated</emphasis> packages.  These are called
-<emphasis>user environments</emphasis> and they are packages
-themselves (though automatically generated by
-<command>nix-env</command>), so they too reside in the Nix store.  For
-instance, in <xref linkend='fig-user-environments' /> the user
-environment <filename>/nix/store/0c1p5z4kda11...-user-env</filename>
-contains a symlink to just Subversion 1.1.2 (arrows in the figure
-indicate symlinks).  This would be what we would obtain if we had done
-
-<screen>
-$ nix-env -i subversion</screen>
-
-on a set of Nix expressions that contained Subversion 1.1.2.</para>
-
-<para>This doesn’t in itself solve the problem, of course; you
-wouldn’t want to type
-<filename>/nix/store/0c1p5z4kda11...-user-env/bin/svn</filename>
-either.  That’s why there are symlinks outside of the store that point
-to the user environments in the store; for instance, the symlinks
-<filename>default-42-link</filename> and
-<filename>default-43-link</filename> in the example.  These are called
-<emphasis>generations</emphasis> since every time you perform a
-<command>nix-env</command> operation, a new user environment is
-generated based on the current one.  For instance, generation 43 was
-created from generation 42 when we did
-
-<screen>
-$ nix-env -i subversion mozilla</screen>
-
-on a set of Nix expressions that contained Mozilla and a new version
-of Subversion.</para>
-
-<para>Generations are grouped together into
-<emphasis>profiles</emphasis> so that different users don’t interfere
-with each other if they don’t want to.  For example:
-
-<screen>
-$ ls -l /nix/var/nix/profiles/
-...
-lrwxrwxrwx  1 eelco ... default-42-link -> /nix/store/0c1p5z4kda11...-user-env
-lrwxrwxrwx  1 eelco ... default-43-link -> /nix/store/3aw2pdyx2jfc...-user-env
-lrwxrwxrwx  1 eelco ... default -> default-43-link</screen>
-
-This shows a profile called <filename>default</filename>.  The file
-<filename>default</filename> itself is actually a symlink that points
-to the current generation.  When we do a <command>nix-env</command>
-operation, a new user environment and generation link are created
-based on the current one, and finally the <filename>default</filename>
-symlink is made to point at the new generation.  This last step is
-atomic on Unix, which explains how we can do atomic upgrades.  (Note
-that the building/installing of new packages doesn’t interfere in
-any way with old packages, since they are stored in different
-locations in the Nix store.)</para>
-
-<para>If you find that you want to undo a <command>nix-env</command>
-operation, you can just do
-
-<screen>
-$ nix-env --rollback</screen>
-
-which will just make the current generation link point at the previous
-link.  E.g., <filename>default</filename> would be made to point at
-<filename>default-42-link</filename>.  You can also switch to a
-specific generation:
-
-<screen>
-$ nix-env --switch-generation 43</screen>
-
-which in this example would roll forward to generation 43 again.  You
-can also see all available generations:
-
-<screen>
-$ nix-env --list-generations</screen></para>
-
-<para>Actually, there is another level of indirection not shown in the
-figure above.  You generally wouldn’t have
-<filename>/nix/var/nix/profiles/<replaceable>some-profile</replaceable>/bin</filename>
-in your <envar>PATH</envar>.  Rather, there is a symlink
-<filename>~/.nix-profile</filename> that points to your current
-profile.  This means that you should put
-<filename>~/.nix-profile/bin</filename> in your <envar>PATH</envar>
-(and indeed, that’s what the initialisation script
-<filename>/nix/etc/profile.d/nix.sh</filename> does).  This makes it
-easier to switch to a different profile.  You can do that using the
-command <command>nix-env --switch-profile</command>:
-
-<screen>
-$ nix-env --switch-profile /nix/var/nix/profiles/my-profile
-
-$ nix-env --switch-profile /nix/var/nix/profiles/default</screen>
-
-These commands switch to the <filename>my-profile</filename> and
-default profile, respectively.  If the profile doesn’t exist, it will
-be created automatically.  You should be careful about storing a
-profile in another location than the <filename>profiles</filename>
-directory, since otherwise it might not be used as a root of the
-garbage collector (see <xref linkend='sec-garbage-collection'
-/>).</para>
-
-<para>All <command>nix-env</command> operations work on the profile
-pointed to by <command>~/.nix-profile</command>, but you can override
-this using the <option>--profile</option> option (abbreviation
-<option>-p</option>):
-
-<screen>
-$ nix-env -p /nix/var/nix/profiles/other-profile -i subversion</screen>
-
-This will <emphasis>not</emphasis> change the
-<command>~/.nix-profile</command> symlink.</para>

-<section xml:id='sec-garbage-collection'><title>Garbage collection</title>
-
-<para><command>nix-env</command> operations such as upgrades

-above) is to create a new user environment that no longer contains
-symlinks to the “deleted” packages.</para>
-
-<para>Of course, since disk space is not infinite, unused packages
-should be removed at some point.  You can do this by running the Nix

-
-<para>Note however that as long as old generations reference a
-package, it will not be deleted.  After all, we wouldn’t be able to
-do a rollback otherwise.  So in order for garbage collection to be
-effective, you should also delete (some) old generations.  Of course,
-this should only be done if you are certain that you will not need to
-roll back.</para>
-
-<para>To delete all old (non-current) generations of your current
-profile:
-
-<screen>
-$ nix-env --delete-generations old</screen>
-
-Instead of <literal>old</literal> you can also specify a list of

-
-<screen>
-$ nix-env --delete-generations 10 11 14</screen>
-
-</para>
-
-<para>After removing appropriate old generations you can run the
-garbage collector as follows:
-
-<screen>
-$ nix-store --gc</screen>
-
-If you are feeling uncertain, you can also first view what files would
-be deleted:
-
-<screen>
-$ nix-store --gc --print-dead</screen>
-
-Likewise, the option <option>--print-live</option> will show the paths
-that <emphasis>won’t</emphasis> be deleted.</para>
-
-<para>There is also a convenient little utility
-<command>nix-collect-garbage</command>, which when invoked with the
-<option>-d</option> (<option>--delete-old</option>) switch deletes all
-old generations of all profiles in
-<filename>/nix/var/nix/profiles</filename>.  So
-
-<screen>
-$ nix-collect-garbage -d</screen>
-
-is a quick and easy way to clean up your system.</para>
-

-
-<section xml:id="ssec-gc-roots"><title>Garbage collector roots</title>
-
-<para>The roots of the garbage collector are all store paths to which
-there are symlinks in the directory
-<filename><replaceable>prefix</replaceable>/nix/var/nix/gcroots</filename>.
-For instance, the following command makes the path
-<filename>/nix/store/d718ef...-foo</filename> a root of the collector:
-
-<screen>
-$ ln -s /nix/store/d718ef...-foo /nix/var/nix/gcroots/bar</screen>

-That is, after this command, the garbage collector will not remove

-
-<para>Subdirectories of

-<section xml:id="sec-channels"><title>Channels</title>
-
-<para>If you want to stay up to date with a set of packages, it’s not
-very convenient to manually download the latest set of Nix expressions
-for those packages, use <command>nix-pull</command> to register
-pre-built binaries (if available), and upgrade using
-<command>nix-env</command>.  Fortunately, there’s a better way:
-<emphasis>Nix channels</emphasis>.</para>
-
-<para>A Nix channel is just a URL that points to a place that contains
-a set of Nix expressions and a manifest.  Using the command <link
-linkend="sec-nix-channel"><command>nix-channel</command></link> you
-can automatically stay up to date with whatever is available at that
-URL.</para>
-
-<para>You can “subscribe” to a channel using
-<command>nix-channel --add</command>, e.g.,
-
-<screen>
-$ nix-channel --add http://nixos.org/channels/nixpkgs-unstable</screen>
-
-subscribes you to a channel that always contains that latest version
-of the Nix Packages collection.  (Instead of
-<literal>nixpkgs-unstable</literal> you could also subscribe to
-<literal>nixpkgs-stable</literal>, which should have a higher level of
-stability, but right now is just outdated.)  Subscribing really just
-means that the URL is added to the file
-<filename>~/.nix-channels</filename>.  Right now there is no command
-to “unsubscribe”; you should just edit that file manually
-and delete the offending URL.</para>
-
-<para>To obtain the latest Nix expressions available in a channel, do
-
-<screen>
-$ nix-channel --update</screen>
-
-This downloads the Nix expressions in every channel (downloaded from
-<literal><replaceable>url</replaceable>/nixexprs.tar.bz2</literal>)
-and registers any available pre-built binaries in every channel
-(by <command>nix-pull</command>ing
-<literal><replaceable>url</replaceable>/MANIFEST</literal>).  It also
-makes the union of each channel’s Nix expressions the default for
-<command>nix-env</command> operations.  Consequently, you can then say
-
-<screen>
-$ nix-env -u '*'</screen>
-
-to upgrade all packages in your profile to the latest versions
-available in the subscribed channels.</para>

-<section xml:id="sec-one-click"><title>One-click installs</title>
-
-<para>Often, when you want to install a specific package (e.g., from
-the <link
-xlink:href="http://nixos.org/nixpkgs/">Nix
-Packages collection</link>), subscribing to a channel is a bit
-cumbersome.  And channels don’t help you at all if you want to install
-an older version of a package than the one provided by the current
-contents of the channel, or a package that has been removed from the
-channel.  That’s when <emphasis>one-click installs</emphasis> come in
-handy: you can just go to the web page that contains the package,
-click on it, and it will be installed with all the necessary
-dependencies.</para>
-
-<para>For instance, you can go to <link
-xlink:href="http://hydra.nixos.org/jobset/nixpkgs/trunk/channel/latest"
-/> and click on any link for the individual packages for your
-platform.  The first time you do this, your browser will ask what to
-do with <literal>application/nix-package</literal> files.  You should
-open them with <filename>/nix/bin/nix-install-package</filename>.
-This will open a window that asks you to confirm that you want to
-install the package.  When you answer <literal>Y</literal>, the
-package and all its dependencies will be installed.  This is a binary
-deployment mechanism — you get packages pre-compiled for the selected
-platform type.</para>
-
-<para>You can also install <literal>application/nix-package</literal>
-files from the command line directly.  See <xref
-linkend='sec-nix-install-package' /> for details.</para>

-
-<section xml:id="sec-sharing-packages"><title>Sharing packages between machines</title>
-
-<para>Sometimes you want to copy a package from one machine to
-another.  Or, you want to install some packages and you know that
-another machine already has some or all of those packages or their
-dependencies.  In that case there are mechanisms to quickly copy
-packages between machines.</para>
-
-<para>The command <command
-linkend="sec-nix-copy-closure">nix-copy-closure</command> copies a Nix
-store path along with all its dependencies to or from another machine
-via the SSH protocol.  It doesn’t copy store paths that are already
-present on the target machine.  For example, the following command
-copies Firefox with all its dependencies:
-
-<screen>
-$ nix-copy-closure --to alice@itchy.example.org $(type -p firefox)</screen>
-
-See <xref linkend='sec-nix-copy-closure' /> for details.</para>
-
-<para>With <command linkend='refsec-nix-store-export'>nix-store
---export</command> and <command
-linkend='refsec-nix-store-import'>nix-store --import</command> you can
-write the closure of a store path (that is, the path and all its
-dependencies) to a file, and then unpack that file into another Nix
-store.  For example,
-
-<screen>
-$ nix-store --export $(nix-store -qR $(type -p firefox)) > firefox.closure</screen>
-
-writes the closure of Firefox to a file.  You can then copy this file
-to another machine and install the closure:
-
-<screen>
-$ nix-store --import &lt; firefox.closure</screen>
-
-Any store paths in the closure that are already present in the target
-store are ignored.  It is also possible to pipe the export into
-another command, e.g. to copy and install a closure directly to/on
-another machine:
-
-<screen>
-$ nix-store --export $(nix-store -qR $(type -p firefox)) | bzip2 | \
-    ssh alice@itchy.example.org "bunzip2 | nix-store --import"</screen>
-
-But note that <command>nix-copy-closure</command> is generally more
-efficient in this example because it only copies paths that are not
-already present in the target Nix store.</para>
-
-<para>Finally, if you can mount the Nix store of a remote machine in
-your local filesystem, Nix can copy paths from the remote Nix store to
-the local Nix store <emphasis>on demand</emphasis>.  For instance,
-suppose that you mount a remote machine containing a Nix store via
-<command
-xlink:href="http://fuse.sourceforge.net/sshfs.html">sshfs</command>:
-
-<screen>
-$ sshfs alice@itchy.example.org:/ /mnt</screen>
-
-You should then set the <envar>NIX_OTHER_STORES</envar> environment
-variable to tell Nix about this remote Nix store:
-
-<screen>
-$ export NIX_OTHER_STORES=/mnt/nix</screen>
-
-Then if you do any Nix operation, e.g.
-
-<screen>
-$ nix-env -i firefox</screen>
-
-and Nix has to build a path that it sees is already present in
-<filename>/mnt/nix</filename>, then it will just copy from there
-instead of building it from source.</para>

-<title>Nix Release Notes</title>
-
-
-<!--==================================================================-->
-
-<section xml:id="ssec-relnotes-1.7"><title>Release 1.7 (TBA)</title>
-
-<para>In addition to the usual bug fixes, this release has the
-following new features:</para>
-
-<itemizedlist>
-
-  <listitem>
-    <para>Antiquotation is now allowed inside of quoted attribute
-    names (e.g. <literal>set."${foo}"</literal>). In the case where
-    the attribute name is just a single antiquotation, the quotes can
-    be dropped (e.g. the above example can be written
-    <literal>set.${foo}</literal>). If an attribute name inside of a
-    set declaration evaluates to <literal>null</literal> (e.g.
-    <literal>{ ${null} = false; }</literal>), then that attribute is
-    not added to the set.</para>
-  </listitem>
-
-  <listitem>
-    <para>Experimental support for cryptographically signed binary
-    caches.  See <link
-    xlink:href="https://github.com/NixOS/nix/commit/0fdf4da0e979f992db75cc17376e455ddc5a96d8">the
-    commit for details</link>.</para>
-  </listitem>
-
-  <listitem>
-    <para>An experimental new substituter,
-    <command>download-via-ssh</command>, that fetches binaries from
-    remote machines via SSH.  Specifying the flags <literal>--option
-    use-ssh-substituter true --option ssh-substituter-hosts
-    <replaceable>user@hostname</replaceable></literal> will cause Nix
-    to download binaries from the specified machine, if it has
-    them.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-store -r</command> and
-    <command>nix-build</command> have a new flag,
-    <option>--check</option>, that builds a previously built
-    derivation again, and prints an error message if the output is not
-    exactly the same. This helps to verify whether a derivation is
-    truly deterministic.  For example:
-
-<screen>
-$ nix-build '&lt;nixpkgs>' -A patchelf
-<replaceable>…</replaceable>
-$ nix-build '&lt;nixpkgs>' -A patchelf --check
-<replaceable>…</replaceable>
-error: derivation `/nix/store/1ipvxs…-patchelf-0.6' may not be deterministic:
-  hash mismatch in output `/nix/store/4pc1dm…-patchelf-0.6.drv'
-</screen>
-
-    </para>
-
-  </listitem>
-
-  <listitem>
-    <para>The <command>nix-instantiate</command> flags
-    <option>--eval-only</option> and <option>--parse-only</option>
-    have been renamed to <option>--eval</option> and
-    <option>--parse</option>, respectively.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-instantiate</command>,
-    <command>nix-build</command> and <command>nix-shell</command> now
-    have a flag <option>--expr</option> (or <option>-E</option>) that
-    allows you to specify the expression to be evaluated as a command
-    line argument.  For instance, <literal>nix-instantiate --eval -E
-    '1 + 2'</literal> will print <literal>3</literal>.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-shell</command> improvements:</para>
-
-    <itemizedlist>
-
-      <listitem>
-        <para>It has a new flag, <option>--packages</option> (or
-        <option>-p</option>), that sets up a build environment
-        containing the specified packages from Nixpkgs. For example,
-        the command
-
-<screen>
-$ nix-shell -p sqlite xorg.libX11 hello
-</screen>
-
-        will start a shell in which the given packages are
-        present.</para>
-      </listitem>
-
-      <listitem>
-        <para>It now uses <filename>shell.nix</filename> as the
-        default expression, falling back to
-        <filename>default.nix</filename> if the former doesn’t
-        exist.  This makes it convenient to have a
-        <filename>shell.nix</filename> in your project to set up a
-        nice development environment.</para>
-      </listitem>
-
-      <listitem>
-        <para>It evaluates the derivation attribute
-        <varname>shellHook</varname>, if set. Since
-        <literal>stdenv</literal> does not normally execute this hook,
-        it allows you to do <command>nix-shell</command>-specific
-        setup.</para>
-      </listitem>
-
-      <listitem>
-        <para>It preserves the user’s timezone setting.</para>
-      </listitem>
-
-    </itemizedlist>
-
-  </listitem>
-
-  <listitem>
-    <para>In chroots, Nix now sets up a <filename>/dev</filename>
-    containing only a minimal set of devices (such as
-    <filename>/dev/null</filename>). Note that it only does this if
-    you <emphasis>don’t</emphasis> have <filename>/dev</filename>
-    listed in your <option>build-chroot-dirs</option> setting;
-    otherwise, it will bind-mount the <literal>/dev</literal> from
-    outside the chroot.</para>
-
-    <para>Similarly, if you don’t have <filename>/dev/pts</filename> listed
-    in <option>build-chroot-dirs</option>, Nix will mount a private
-    <literal>devpts</literal> filesystem on the chroot’s
-    <filename>/dev/pts</filename>.</para>
-
-  </listitem>
-
-  <listitem>
-    <para>New built-in function: <function>builtins.toJSON</function>,
-    which returns a JSON representation of a value.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-env -q</command> has a new flag
-    <option>--json</option> to print a JSON representation of the
-    installed or available packages.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-env</command> now supports meta attributes with
-    more complex values, such as attribute sets.</para>
-  </listitem>
-
-  <listitem>
-    <para>The <option>-A</option> flag now allows attribute names with
-    dots in them, e.g.
-
-<screen>
-$ nix-instantiate --eval '&lt;nixos>' -A 'config.systemd.units."nscd.service".text'
-</screen>
-
-    </para>
-  </listitem>
-
-  <listitem>
-    <para>The <option>--max-freed</option> option to
-    <command>nix-store --gc</command> now accepts a unit
-    specifier. For example, <literal>nix-store --gc --max-freed
-    1G</literal> will free up to 1 gigabyte of disk space.</para>
-  </listitem>
-
-  <listitem>
-    <para>Nix now heuristically detects whether a build failure was
-    due to a disk-full condition. In that case, the build is not
-    flagged as “permanently failed”. This is mostly useful for Hydra,
-    which needs to distinguish between permanent and transient build
-    failures.</para>
-  </listitem>
-
-  <listitem>
-    <para>There is a new symbol <literal>__curPos</literal> that
-    expands to an attribute set containing its file name and line and
-    column numbers, e.g. <literal>{ file = "foo.nix"; line = 10;
-    column = 5; }</literal>.  There also is a new builtin function,
-    <varname>unsafeGetAttrPos</varname>, that returns the position of
-    an attribute.  This is used by Nixpkgs to provide location
-    information in error messages, e.g.
-
-<screen>
-$ nix-build '&lt;nixpkgs>' -A libreoffice --argstr system x86_64-darwin
-error: the package ‘libreoffice-4.0.5.2’ in ‘.../applications/office/libreoffice/default.nix:263’
-  is not supported on ‘x86_64-darwin’
-</screen>
-
-    </para>
-  </listitem>
-
-  <listitem>
-    <para>The garbage collector is now more concurrent with other Nix
-    processes because it releases certain locks earlier.</para>
-  </listitem>
-
-  <listitem>
-    <para>The binary tarball installer has been improved.  You can now
-    install Nix by running:
-
-<screen>
-$ bash &lt;(curl https://nixos.org/nix/install)
-</screen>
-
-    </para>
-  </listitem>
-
-  <listitem>
-    <para>The command <command>nix-setuid-helper</command> is
-    gone.</para>
-  </listitem>
-
-  <listitem>
-    <para>Nix no longer uses Automake, but instead has a
-    non-recursive, GNU Make-based build system.</para>
-  </listitem>
-
-  <listitem>
-    <para>All installed libraries now have the prefix
-    <literal>libnix</literal>.  In particular, this gets rid of
-    <literal>libutil</literal>, which could clash with libraries with
-    the same name from other packages.</para>
-  </listitem>

-<section xml:id="ssec-relnotes-1.6.1"><title>Release 1.6.1 (October 28, 2013)</title>
-
-<para>This is primarily a bug fix release.  Changes of interest
-are:</para>
-
-<itemizedlist>
-
-  <listitem>
-    <para>Nix 1.6 accidentally changed the semantics of antiquoted
-    paths in strings, such as <literal>"${/foo}/bar"</literal>.  This
-    release reverts to the Nix 1.5.3 behaviour.</para>
-  </listitem>
-
-  <listitem>
-    <para>Previously, Nix optimised expressions such as
-    <literal>"${<replaceable>expr</replaceable>}"</literal> to
-    <replaceable>expr</replaceable>.  Thus it neither checked whether
-    <replaceable>expr</replaceable> could be coerced to a string, nor
-    applied such coercions.  This meant that
-    <literal>"${123}"</literal> evaluatued to <literal>123</literal>,
-    and <literal>"${./foo}"</literal> evaluated to
-    <literal>./foo</literal> (even though
-    <literal>"${./foo} "</literal> evaluates to
-    <literal>"/nix/store/<replaceable>hash</replaceable>-foo "</literal>).
-    Nix now checks the type of antiquoted expressions and
-    applies coercions.</para>
-  </listitem>
-
-  <listitem>
-    <para>Nix now shows the exact position of undefined variables.  In
-    particular, undefined variable errors in a <literal>with</literal>
-    previously didn't show <emphasis>any</emphasis> position
-    information, so this makes it a lot easier to fix such
-    errors.</para>
-  </listitem>
-
-  <listitem>
-    <para>Undefined variables are now treated consistently.
-    Previously, the <function>tryEval</function> function would catch
-    undefined variables inside a <literal>with</literal> but not
-    outside.  Now <function>tryEval</function> never catches undefined
-    variables.</para>
-  </listitem>
-
-  <listitem>
-    <para>Bash completion in <command>nix-shell</command> now works
-    correctly.</para>
-  </listitem>
-
-  <listitem>
-    <para>Stack traces are less verbose: they no longer show calls to
-    builtin functions and only show a single line for each derivation
-    on the call stack.</para>
-  </listitem>
-
-  <listitem>
-    <para>New built-in function: <function>builtins.typeOf</function>,
-    which returns the type of its argument as a string.</para>
-  </listitem>
-
-</itemizedlist>

-<section xml:id="ssec-relnotes-1.6.0"><title>Release 1.6 (September 10, 2013)</title>
-
-<para>In addition to the usual bug fixes, this release has several new
-features:</para>
-
-<itemizedlist>
-
-  <listitem>
-    <para>The command <command>nix-build --run-env</command> has been
-    renamed to <command>nix-shell</command>.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-shell</command> now sources
-    <filename>$stdenv/setup</filename> <emphasis>inside</emphasis> the
-    interactive shell, rather than in a parent shell.  This ensures
-    that shell functions defined by <literal>stdenv</literal> can be
-    used in the interactive shell.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-shell</command> has a new flag
-    <option>--pure</option> to clear the environment, so you get an
-    environment that more closely corresponds to the “real” Nix build.
-    </para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-shell</command> now sets the shell prompt
-    (<envar>PS1</envar>) to ensure that Nix shells are distinguishable
-    from your regular shells.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-env</command> no longer requires a
-    <literal>*</literal> argument to match all packages, so
-    <literal>nix-env -qa</literal> is equivalent to <literal>nix-env
-    -qa '*'</literal>.</para>
-  </listitem>
-
-  <listitem>
-    <para><command>nix-env -i</command> has a new flag
-    <option>--remove-all</option> (<option>-r</option>) to remove all
-    previous packages from the profile.  This makes it easier to do
-    declarative package management similar to NixOS’s
-    <option>environment.systemPackages</option>.  For instance, if you
-    have a specification <filename>my-packages.nix</filename> like this:
-
-<programlisting>
-with import &lt;nixpkgs> {};
-[ thunderbird
-  geeqie
-  ...
-]
-</programlisting>
-
-    then after any change to this file, you can run:
-
-<screen>
-$ nix-env -f my-packages.nix -ir
-</screen>
-
-    to update your profile to match the specification.</para>
-  </listitem>
-
-  <listitem>
-    <para>The ‘<literal>with</literal>’ language construct is now more
-    lazy.  It only evaluates its argument if a variable might actually
-    refer to an attribute in the argument.  For instance, this now
-    works:
-
-<programlisting>
-let
-  pkgs = with pkgs; { foo = "old"; bar = foo; } // overrides;
-  overrides = { foo = "new"; };
-in pkgs.bar
-</programlisting>
-
-    This evaluates to <literal>"new"</literal>, while previously it
-    gave an “infinite recursion” error.</para>
-  </listitem>
-
-  <listitem>
-    <para>Nix now has proper integer arithmetic operators. For
-    instance, you can write <literal>x + y</literal> instead of
-    <literal>builtins.add x y</literal>, or <literal>x &lt;
-    y</literal> instead of <literal>builtins.lessThan x y</literal>.
-    The comparison operators also work on strings.</para>
-  </listitem>
-
-  <listitem>
-    <para>On 64-bit systems, Nix integers are now 64 bits rather than
-    32 bits.</para>
-  </listitem>
-
-  <listitem>
-    <para>When using the Nix daemon, the <command>nix-daemon</command>
-    worker process now runs on the same CPU as the client, on systems
-    that support setting CPU affinity.  This gives a significant speedup
-    on some systems.</para>
-  </listitem>
-
-  <listitem>
-    <para>If a stack overflow occurs in the Nix evaluator, you now get
-    a proper error message (rather than “Segmentation fault”) on some
-    systems.</para>
-  </listitem>
-
-  <listitem>
-    <para>In addition to directories, you can now bind-mount regular
-    files in chroots through the (now misnamed) option
-    <option>build-chroot-dirs</option>.</para>

-
-<itemizedlist>
-
-  <listitem>
-    <para>Yet another security bug involving hard links to files
-    outside the store was fixed.  This bug only affected multi-user

-    <para>The default binary cache URL has changed from

-    <uri>http://cache.nixos.org</uri>.  The latter is hosted on Amazon
-    CloudFront (courtesy of <link
-    xlink:href="http://www.logicblox.com/">LogicBlox</link>) and
-    should provide better performance for users in both Europe and
-    North America.</para>
-  </listitem>
-
-  <listitem>
-    <para>The binary cache substituter now prints a warning message if
-    fetching information from the cache takes more than five seconds.
-    Thus network or server problems no longer make Nix appear to just
-    hang.</para>
-  </listitem>

-      Also, if a function is called with an unexpected argument, Nix

-
-<para>This release has the following improvements and changes:</para>
-
-<itemizedlist>
-
-  <listitem>
-    <para>Nix has a new binary substituter mechanism: the
-    <emphasis>binary cache</emphasis>.  A binary cache contains
-    pre-built binaries of Nix packages.  Whenever Nix wants to build a
-    missing Nix store path, it will check a set of binary caches to
-    see if any of them has a pre-built binary of that path.  The
-    configuration setting <option>binary-caches</option> contains a
-    list of URLs of binary caches.  For instance, doing
-<screen>
-$ nix-env -i thunderbird --option binary-caches http://cache.nixos.org
-</screen>
-    will install Thunderbird and its dependencies, using the available
-    pre-built binaries in <uri>http://cache.nixos.org</uri>.
-    The main advantage over the old “manifest”-based method of getting
-    pre-built binaries is that you don’t have to worry about your
-    manifest being in sync with the Nix expressions you’re installing
-    from; i.e., you don’t need to run <command>nix-pull</command> to
-    update your manifest.  It’s also more scalable because you don’t
-    need to redownload a giant manifest file every time.
-    </para>
-
-    <para>A Nix channel can provide a binary cache URL that will be
-    used automatically if you subscribe to that channel.  If you use
-    the Nixpkgs or NixOS channels
-    (<uri>http://nixos.org/channels</uri>) you automatically get the
-    cache <uri>http://cache.nixos.org</uri>.</para>
-
-    <para>Binary caches are created using <command>nix-push</command>.
-    For details on the operation and format of binary caches, see the

-    <para>Multiple output support should now be usable.  A derivation

-    This will cause Nix to pass the intended store path of each output
-    to the builder through the environment variables

-
-<para>This release has the following improvements:</para>
-
-<itemizedlist>
-
-  <listitem>
-    <para>On Linux, when doing a chroot build, Nix now uses various
-    namespace features provided by the Linux kernel to improve
-    build isolation.  Namely:
-    <itemizedlist>
-      <listitem><para>The private network namespace ensures that
-      builders cannot talk to the outside world (or vice versa): each
-      build only sees a private loopback interface.  This also means
-      that two concurrent builds can listen on the same port (e.g. as
-      part of a test) without conflicting with each
-      other.</para></listitem>
-      <listitem><para>The PID namespace causes each build to start as
-      PID 1.  Processes outside of the chroot are not visible to those
-      on the inside.  On the other hand, processes inside the chroot
-      <emphasis>are</emphasis> visible from the outside (though with
-      different PIDs).</para></listitem>
-      <listitem><para>The IPC namespace prevents the builder from
-      communicating with outside processes using SysV IPC mechanisms
-      (shared memory, message queues, semaphores).  It also ensures
-      that all IPC objects are destroyed when the builder
-      exits.</para></listitem>
-      <listitem><para>The UTS namespace ensures that builders see a
-      hostname of <literal>localhost</literal> rather than the actual
-      hostname.</para></listitem>
-      <listitem><para>The private mount namespace was already used by
-      Nix to ensure that the bind-mounts used to set up the chroot are
-      cleaned up automatically.</para></listitem>
-    </itemizedlist>
-    </para>
-  </listitem>
-
-  <listitem>
-    <para>Build logs are now compressed using
-    <command>bzip2</command>.  The command <command>nix-store
-    -l</command> decompresses them on the fly.  This can be disabled
-    by setting the option <literal>build-compress-log</literal> to
-    <literal>false</literal>.</para>
-  </listitem>
-
-  <listitem>
-    <para>The creation of build logs in
-    <filename>/nix/var/log/nix/drvs</filename> can be disabled by
-    setting the new option <literal>build-keep-log</literal> to
-    <literal>false</literal>.  This is useful, for instance, for Hydra
-    build machines.</para>
-  </listitem>
-
-  <listitem>
-    <para>Nix now reserves some space in
-    <filename>/nix/var/nix/db/reserved</filename> to ensure that the
-    garbage collector can run successfully if the disk is full.  This
-    is necessary because SQLite transactions fail if the disk is
-    full.</para>
-  </listitem>
-
-  <listitem>
-    <para>Added a basic <function>fetchurl</function> function.  This
-    is not intended to replace the <function>fetchurl</function> in
-    Nixpkgs, but is useful for bootstrapping; e.g., it will allow us
-    to get rid of the bootstrap binaries in the Nixpkgs source tree
-    and download them instead.  You can use it by doing
-    <literal>import &lt;nix/fetchurl.nix> { url =
-    <replaceable>url</replaceable>; sha256 =
-    "<replaceable>hash</replaceable>"; }</literal>. (Shea Levy)</para>

-
-<para>There have been numerous improvements and bug fixes since the
-previous release.  Here are the most significant:</para>
-
-<itemizedlist>
-
-  <listitem>
-    <para>Nix can now optionally use the Boehm garbage collector.
-    This significantly reduces the Nix evaluator’s memory footprint,
-    especially when evaluating large NixOS system configurations.  It
-    can be enabled using the <option>--enable-gc</option> configure
-    option.</para>
-  </listitem>
-
-  <listitem>
-    <para>Nix now uses SQLite for its database.  This is faster and
-    more flexible than the old <emphasis>ad hoc</emphasis> format.
-    SQLite is also used to cache the manifests in
-    <filename>/nix/var/nix/manifests</filename>, resulting in a
-    significant speedup.</para>
-  </listitem>
-
-  <listitem>
-    <para>Nix now has an search path for expressions.  The search path
-    is set using the environment variable <envar>NIX_PATH</envar> and
-    the <option>-I</option> command line option.  In Nix expressions,
-    paths between angle brackets are used to specify files that must
-    be looked up in the search path.  For instance, the expression
-    <literal>&lt;nixpkgs/default.nix></literal> looks for a file
-    <filename>nixpkgs/default.nix</filename> relative to every element
-    in the search path.</para>
-  </listitem>
-
-  <listitem>
-    <para>The new command <command>nix-build --run-env</command>
-    builds all dependencies of a derivation, then starts a shell in an
-    environment containing all variables from the derivation.  This is
-    useful for reproducing the environment of a derivation for
-    development.</para>
-  </listitem>
-
-  <listitem>
-    <para>The new command <command>nix-store --verify-path</command>
-    verifies that the contents of a store path have not
-    changed.</para>
-  </listitem>
-
-  <listitem>
-    <para>The new command <command>nix-store --print-env</command>
-    prints out the environment of a derivation in a format that can be
-    evaluated by a shell.</para>
-  </listitem>
-
-  <listitem>
-    <para>Attribute names can now be arbitrary strings.  For instance,
-    you can write <literal>{ "foo-1.2" = …; "bla bla" = …; }."bla
-    bla"</literal>.</para>
-  </listitem>
-
-  <listitem>
-    <para>Attribute selection can now provide a default value using
-    the <literal>or</literal> operator.  For instance, the expression
-    <literal>x.y.z or e</literal> evaluates to the attribute
-    <literal>x.y.z</literal> if it exists, and <literal>e</literal>
-    otherwise.</para>
-  </listitem>
-
-  <listitem>
-    <para>The right-hand side of the <literal>?</literal> operator can
-    now be an attribute path, e.g., <literal>attrs ?
-    a.b.c</literal>.</para>
-  </listitem>
-
-  <listitem>
-    <para>On Linux, Nix will now make files in the Nix store immutable
-    on filesystems that support it.  This prevents accidental
-    modification of files in the store by the root user.</para>
-  </listitem>
-
-  <listitem>
-    <para>Nix has preliminary support for derivations with multiple
-    outputs.  This is useful because it allows parts of a package to
-    be deployed and garbage-collected separately.  For instance,
-    development parts of a package such as header files or static
-    libraries would typically not be part of the closure of an
-    application, resulting in reduced disk usage and installation
-    time.</para>
-  </listitem>
-
-  <listitem>
-    <para>The Nix store garbage collector is faster and holds the
-    global lock for a shorter amount of time.</para>
-  </listitem>
-
-  <listitem>
-    <para>The option <option>--timeout</option> (corresponding to the
-    configuration setting <literal>build-timeout</literal>) allows you
-    to set an absolute timeout on builds — if a build runs for more than
-    the given number of seconds, it is terminated.  This is useful for
-    recovering automatically from builds that are stuck in an infinite
-    loop but keep producing output, and for which
-    <literal>--max-silent-time</literal> is ineffective.</para>

-    <para>The Nix expression evaluator is now much faster in most

-  <listitem>
-    <para>
-      Support for configurable parallelism inside builders.  Build
-      scripts have always had the ability to perform multiple build
-      actions in parallel (for instance, by running <command>make -j
-      2</command>), but this was not desirable because the number of
-      actions to be performed in parallel was not configurable.  Nix

-      <replaceable>N</replaceable></option> as well as a configuration
-      setting <varname>build-cores =

-      environment variable <envar>NIX_BUILD_CORES</envar> to be set to
-      <replaceable>N</replaceable> when the builder is invoked.  The
-      builder can use this at its discretion to perform a parallel
-      build, e.g., by calling <command>make -j
-      <replaceable>N</replaceable></command>.  In Nixpkgs, this can be
-      enabled on a per-package basis by setting the derivation

-
-  <listitem>
-    <para>Nix no longer uses Berkeley DB to store Nix store metadata.
-    The principal advantages of the new storage scheme are: it works
-    properly over decent implementations of NFS (allowing Nix stores
-    to be shared between multiple machines); no recovery is needed
-    when a Nix process crashes; no write access is needed for
-    read-only operations; no more running out of Berkeley DB locks on
-    certain operations.</para>
-
-    <para>You still need to compile Nix with Berkeley DB support if
-    you want Nix to automatically convert your old Nix store to the
-    new schema.  If you don’t need this, you can build Nix with the
-    <filename>configure</filename> option
-    <option>--disable-old-db-compat</option>.</para>
-
-    <para>After the automatic conversion to the new schema, you can
-    delete the old Berkeley DB files:
-
-    <screen>
-$ cd /nix/var/nix/db
-$ rm __db* log.* derivers references referrers reserved validpaths DB_CONFIG</screen>
-
-    The new metadata is stored in the directories
-    <filename>/nix/var/nix/db/info</filename> and
-    <filename>/nix/var/nix/db/referrer</filename>.  Though the
-    metadata is stored in human-readable plain-text files, they are
-    not intended to be human-editable, as Nix is rather strict about
-    the format.</para>
-
-    <para>The new storage schema may or may not require less disk
-    space than the Berkeley DB environment, mostly depending on the
-    cluster size of your file system.  With 1 KiB clusters (which
-    seems to be the <literal>ext3</literal> default nowadays) it
-    usually takes up much less space.</para>
-  </listitem>
-
-  <listitem><para>There is a new substituter that copies paths
-  directly from other (remote) Nix stores mounted somewhere in the
-  filesystem.  For instance, you can speed up an installation by
-  mounting some remote Nix store that already has the packages in
-  question via NFS or <literal>sshfs</literal>.  The environment
-  variable <envar>NIX_OTHER_STORES</envar> specifies the locations of
-  the remote Nix directories,
-  e.g. <literal>/mnt/remote-fs/nix</literal>.</para></listitem>
-
-  <listitem><para>New <command>nix-store</command> operations
-  <option>--dump-db</option> and <option>--load-db</option> to dump
-  and reload the Nix database.</para></listitem>
-
-  <listitem><para>The garbage collector has a number of new options to
-  allow only some of the garbage to be deleted.  The option
-  <option>--max-freed <replaceable>N</replaceable></option> tells the
-  collector to stop after at least <replaceable>N</replaceable> bytes
-  have been deleted.  The option <option>--max-links
-  <replaceable>N</replaceable></option> tells it to stop after the
-  link count on <filename>/nix/store</filename> has dropped below
-  <replaceable>N</replaceable>.  This is useful for very large Nix
-  stores on filesystems with a 32000 subdirectories limit (like
-  <literal>ext3</literal>).  The option <option>--use-atime</option>
-  causes store paths to be deleted in order of ascending last access
-  time.  This allows non-recently used stuff to be deleted.  The
-  option <option>--max-atime <replaceable>time</replaceable></option>
-  specifies an upper limit to the last accessed time of paths that may
-  be deleted.  For instance,
-
-    <screen>
-    $ nix-store --gc -v --max-atime $(date +%s -d "2 months ago")</screen>
-
-  deletes everything that hasn’t been accessed in two months.</para></listitem>
-
-  <listitem><para><command>nix-env</command> now uses optimistic
-  profile locking when performing an operation like installing or
-  upgrading, instead of setting an exclusive lock on the profile.
-  This allows multiple <command>nix-env -i / -u / -e</command>
-  operations on the same profile in parallel.  If a
-  <command>nix-env</command> operation sees at the end that the profile
-  was changed in the meantime by another process, it will just
-  restart.  This is generally cheap because the build results are
-  still in the Nix store.</para></listitem>

-<section xml:id="ssec-relnotes-0.11"><title>Release 0.11 (December 31,
-2007)</title>
-
-<para>Nix 0.11 has many improvements over the previous stable release.
-The most important improvement is secure multi-user support.  It also
-features many usability enhancements and language extensions, many of
-them prompted by NixOS, the purely functional Linux distribution based
-on Nix.  Here is an (incomplete) list:</para>
-
-
-<itemizedlist>
-
-
-  <listitem><para>Secure multi-user support.  A single Nix store can
-  now be shared between multiple (possible untrusted) users.  This is
-  an important feature for NixOS, where it allows non-root users to
-  install software.  The old setuid method for sharing a store between
-  multiple users has been removed.  Details for setting up a
-  multi-user store can be found in the manual.</para></listitem>
-
-
-  <listitem><para>The new command <command>nix-copy-closure</command>
-  gives you an easy and efficient way to exchange software between
-  machines.  It copies the missing parts of the closure of a set of
-  store path to or from a remote machine via
-  <command>ssh</command>.</para></listitem>
-
-
-  <listitem><para>A new kind of string literal: strings between double
-  single-quotes (<literal>''</literal>) have indentation
-  “intelligently” removed.  This allows large strings (such as shell
-  scripts or configuration file fragments in NixOS) to cleanly follow
-  the indentation of the surrounding expression.  It also requires
-  much less escaping, since <literal>''</literal> is less common in
-  most languages than <literal>"</literal>.</para></listitem>
-
-
-  <listitem><para><command>nix-env</command> <option>--set</option>
-  modifies the current generation of a profile so that it contains
-  exactly the specified derivation, and nothing else.  For example,
-  <literal>nix-env -p /nix/var/nix/profiles/browser --set
-  firefox</literal> lets the profile named
-  <filename>browser</filename> contain just Firefox.</para></listitem>
-
-
-  <listitem><para><command>nix-env</command> now maintains
-  meta-information about installed packages in profiles.  The
-  meta-information is the contents of the <varname>meta</varname>
-  attribute of derivations, such as <varname>description</varname> or
-  <varname>homepage</varname>.  The command <literal>nix-env -q --xml
-  --meta</literal> shows all meta-information.</para></listitem>
-
-
-  <listitem><para><command>nix-env</command> now uses the
-  <varname>meta.priority</varname> attribute of derivations to resolve
-  filename collisions between packages.  Lower priority values denote
-  a higher priority.  For instance, the GCC wrapper package and the
-  Binutils package in Nixpkgs both have a file
-  <filename>bin/ld</filename>, so previously if you tried to install
-  both you would get a collision.  Now, on the other hand, the GCC
-  wrapper declares a higher priority than Binutils, so the former’s
-  <filename>bin/ld</filename> is symlinked in the user
-  environment.</para></listitem>
-
-
-  <listitem><para><command>nix-env -i / -u</command>: instead of
-  breaking package ties by version, break them by priority and version
-  number.  That is, if there are multiple packages with the same name,
-  then pick the package with the highest priority, and only use the
-  version if there are multiple packages with the same
-  priority.</para>
-
-  <para>This makes it possible to mark specific versions/variant in
-  Nixpkgs more or less desirable than others.  A typical example would
-  be a beta version of some package (e.g.,
-  <literal>gcc-4.2.0rc1</literal>) which should not be installed even
-  though it is the highest version, except when it is explicitly
-  selected (e.g., <literal>nix-env -i
-  gcc-4.2.0rc1</literal>).</para></listitem>
-
-
-  <listitem><para><command>nix-env --set-flag</command> allows meta
-  attributes of installed packages to be modified.  There are several
-  attributes that can be usefully modified, because they affect the
-  behaviour of <command>nix-env</command> or the user environment
-  build script:
-
-    <itemizedlist>
-
-      <listitem><para><varname>meta.priority</varname> can be changed
-      to resolve filename clashes (see above).</para></listitem>
-
-      <listitem><para><varname>meta.keep</varname> can be set to
-      <literal>true</literal> to prevent the package from being
-      upgraded or replaced.  Useful if you want to hang on to an older
-      version of a package.</para></listitem>
-
-      <listitem><para><varname>meta.active</varname> can be set to
-      <literal>false</literal> to “disable” the package.  That is, no
-      symlinks will be generated to the files of the package, but it
-      remains part of the profile (so it won’t be garbage-collected).
-      Set it back to <literal>true</literal> to re-enable the
-      package.</para></listitem>
-
-    </itemizedlist>
-
-  </para></listitem>
-
-
-  <listitem><para><command>nix-env -q</command> now has a flag
-  <option>--prebuilt-only</option> (<option>-b</option>) that causes

-  downloaded from somewhere).  In other words, it shows the packages
-  that can be installed “quickly”, i.e., don’t need to be built from
-  source.  The <option>-b</option> flag is also available in

-
-<para>Nix 0.8 has the following improvements:
-
-<itemizedlist>
-
-  <listitem><para>The cryptographic hashes used in store paths are now
-  160 bits long, but encoded in base-32 so that they are still only 32
-  characters long (e.g.,
-  <filename>/nix/store/csw87wag8bqlqk7ipllbwypb14xainap-atk-1.9.0</filename>).
-  (This is actually a 160 bit truncation of a SHA-256
-  hash.)</para></listitem>
-
-  <listitem><para>Big cleanups and simplifications of the basic store
-  semantics.  The notion of “closure store expressions” is gone (and
-  so is the notion of “successors”); the file system references of a
-  store path are now just stored in the database.</para>
-
-  <para>For instance, given any store path, you can query its closure:
-
-  <screen>
-$ nix-store -qR $(which firefox)
-... lots of paths ...</screen>
-
-  Also, Nix now remembers for each store path the derivation that
-  built it (the “deriver”):
-
-  <screen>
-$ nix-store -qR $(which firefox)
-/nix/store/4b0jx7vq80l9aqcnkszxhymsf1ffa5jd-firefox-1.0.1.drv</screen>
-
-  So to see the build-time dependencies, you can do
-
-  <screen>
-$ nix-store -qR $(nix-store -qd $(which firefox))</screen>
-
-  or, in a nicer format:
-
-  <screen>
-$ nix-store -q --tree $(nix-store -qd $(which firefox))</screen>
-
-  </para>
-
-  <para>File system references are also stored in reverse.  For
-  instance, you can query all paths that directly or indirectly use a
-  certain Glibc:
-
-  <screen>
-$ nix-store -q --referrers-closure \
-    /nix/store/8lz9yc6zgmc0vlqmn2ipcpkjlmbi51vv-glibc-2.3.4</screen>
-
-  </para>
-
-  </listitem>
-
-  <listitem><para>The concept of fixed-output derivations has been
-  formalised.  Previously, functions such as
-  <function>fetchurl</function> in Nixpkgs used a hack (namely,
-  explicitly specifying a store path hash) to prevent changes to, say,
-  the URL of the file from propagating upwards through the dependency
-  graph, causing rebuilds of everything.  This can now be done cleanly
-  by specifying the <varname>outputHash</varname> and
-  <varname>outputHashAlgo</varname> attributes.  Nix itself checks
-  that the content of the output has the specified hash.  (This is
-  important for maintaining certain invariants necessary for future

-  — see, e.g., <link

-  All you have to do is associate
-  <filename>/nix/bin/nix-install-package</filename> with the MIME type
-  <literal>application/nix-package</literal> (or the extension
-  <filename>.nixpkg</filename>), and clicking on a package link will
-  cause it to be installed, with all appropriate dependencies.  If you

-  subscribing to a channel.</para></listitem>
-
-  <listitem><para><command>nix-store -r

-<title>Troubleshooting</title>

-
-<section><title>Collisions in <command>nix-env</command></title>
-
-<para>Symptom: when installing or upgrading, you get an error message such as
-
-<screen>
-$ nix-env -i docbook-xml
-...
-adding /nix/store/s5hyxgm62gk2...-docbook-xml-4.2

-  at /nix/store/...-builder.pl line 62.</screen>
-
-</para>
-
-<para>The cause is that two installed packages in the user environment
-have overlapping filenames (e.g.,
-<filename>xml/dtd/docbook/calstblx.dtd</filename>.  This usually
-happens when you accidentally try to install two versions of the same
-package.  For instance, in the example above, the Nix Packages
-collection contains two versions of <literal>docbook-xml</literal>, so
-<command>nix-env -i</command> will try to install both.  The default
-user environment builder has no way to way to resolve such conflicts,
-so it just gives up.</para>
-
-<para>Solution: remove one of the offending packages from the user
-environment (if already installed) using <command>nix-env
--e</command>, or specify exactly which version should be installed
-(e.g., <literal>nix-env -i docbook-xml-4.2</literal>).</para>
-
-<para>Alternatively, you can modify the user environment builder
-script (in
-<filename><replaceable>prefix</replaceable>/share/nix/corepkgs/buildenv/builder.pl</filename>)
-to implement some conflict resolution policy.  E.g., the script could
-be modified to rename conflicting file names, or to pick one over the
-other.</para>

-
-
-<para>Symptom: when building something, you get an error message such as
-
-<screen>
-...
-<literal>mkdir: cannot create directory `/nix/store/<replaceable>name</replaceable>': Too many links</literal></screen>
-
-</para>
-
-<para>This is usually because you have more than 32,000 subdirectories
-in <filename>/nix/store</filename>, as can be seen using <command>ls
--l</command>:
-
-<screen>
-$ ls -l /nix/store
-drwxrwxrwt 32000 nix nix 4620288 Sep 8 15:08 store</screen>
-
-The <literal>ext2</literal> file system is limited to an inode link
-count of 32,000 (each subdirectory increasing the count by one).
-Furthermore, the <literal>st_nlink</literal> field of the
-<function>stat</function> system call is a 16-bit value.</para>
-
-<para>This only happens on very large Nix installations (such as build
-machines).</para>
-
-<para>Quick solution: run the garbage collector.  You may want to use
-the <option>--max-links</option> option.</para>
-
-<para>Real solution: put the Nix store on a file system that supports
-more than 32,000 subdirectories per directory, such as ReiserFS.
-(This doesn’t solve the <literal>st_nlink</literal> limit, but
-ReiserFS lies to the kernel by reporting a link count of 1 if it
-exceeds the limit.)</para>

-<title>Writing Nix Expressions</title>
-
-
-<para>This chapter shows you how to write Nix expressions, which are
-the things that tell Nix how to build packages.  It starts with a
-simple example (a Nix expression for GNU Hello), and then moves
-on to a more in-depth look at the Nix expression language.</para>
-
-<note><para>This chapter is mostly about the Nix expression language.
-For more extensive information on adding packages to the Nix Packages
-collection (such as functions in the standard environment and coding
-conventions), please consult <link
-xlink:href="http://nixos.org/nixpkgs/manual/">its
-manual</link>.</para></note>

-
-<section><title>A simple Nix expression</title>
-
-<para>This section shows how to add and test the <link
-xlink:href='http://www.gnu.org/software/hello/hello.html'>GNU Hello
-package</link> to the Nix Packages collection.  Hello is a program
-that prints out the text <quote>Hello, world!</quote>.</para>
-
-<para>To add a package to the Nix Packages collection, you generally
-need to do three things:
-
-<orderedlist>
-
-  <listitem><para>Write a Nix expression for the package.  This is a
-  file that describes all the inputs involved in building the package,
-  such as dependencies, sources, and so on.</para></listitem>
-
-  <listitem><para>Write a <emphasis>builder</emphasis>.  This is a
-  shell script<footnote><para>In fact, it can be written in any
-  language, but typically it's a <command>bash</command> shell
-  script.</para></footnote> that actually builds the package from
-  the inputs.</para></listitem>
-
-  <listitem><para>Add the package to the file
-  <filename>pkgs/top-level/all-packages.nix</filename>.  The Nix
-  expression written in the first step is a
-  <emphasis>function</emphasis>; it requires other packages in order
-  to build it.  In this step you put it all together, i.e., you call
-  the function with the right arguments to build the actual
-  package.</para></listitem>
-
-</orderedlist>
-
-</para>
-
-
-<section><title>The Nix expression</title>
-
-<example xml:id='ex-hello-nix'><title>Nix expression for GNU Hello
-(<filename>default.nix</filename>)</title>
-<programlisting>
-{ stdenv, fetchurl, perl }: <co xml:id='ex-hello-nix-co-1' />
-
-stdenv.mkDerivation { <co xml:id='ex-hello-nix-co-2' />

-    md5 = "70c9ccf9fac07f762c24f2df2290784d";
-  };
-  inherit perl; <co xml:id='ex-hello-nix-co-6' />
-}</programlisting>
-</example>
-
-<para><xref linkend='ex-hello-nix' /> shows a Nix expression for GNU
-Hello.  It's actually already in the Nix Packages collection in
-<filename>pkgs/applications/misc/hello/ex-1/default.nix</filename>.
-It is customary to place each package in a separate directory and call
-the single Nix expression in that directory
-<filename>default.nix</filename>.  The file has the following elements
-(referenced from the figure by number):
-
-<calloutlist>
-
-  <callout arearefs='ex-hello-nix-co-1'>
-
-    <para>This states that the expression is a
-    <emphasis>function</emphasis> that expects to be called with three
-    arguments: <varname>stdenv</varname>, <varname>fetchurl</varname>,
-    and <varname>perl</varname>.  They are needed to build Hello, but
-    we don't know how to build them here; that's why they are function
-    arguments.  <varname>stdenv</varname> is a package that is used
-    by almost all Nix Packages packages; it provides a
-    <quote>standard</quote> environment consisting of the things you
-    would expect in a basic Unix environment: a C/C++ compiler (GCC,
-    to be precise), the Bash shell, fundamental Unix tools such as
-    <command>cp</command>, <command>grep</command>,
-    <command>tar</command>, etc.  <varname>fetchurl</varname> is a
-    function that downloads files.  <varname>perl</varname> is the
-    Perl interpreter.</para>
-
-    <para>Nix functions generally have the form <literal>{ x, y, ...,
-    z }: e</literal> where <varname>x</varname>, <varname>y</varname>,
-    etc. are the names of the expected arguments, and where
-    <replaceable>e</replaceable> is the body of the function.  So
-    here, the entire remainder of the file is the body of the
-    function; when given the required arguments, the body should
-    describe how to build an instance of the Hello package.</para>
-
-  </callout>
-
-  <callout arearefs='ex-hello-nix-co-2'>
-
-    <para>So we have to build a package.  Building something from
-    other stuff is called a <emphasis>derivation</emphasis> in Nix (as
-    opposed to sources, which are built by humans instead of
-    computers).  We perform a derivation by calling
-    <varname>stdenv.mkDerivation</varname>.
-    <varname>mkDerivation</varname> is a function provided by
-    <varname>stdenv</varname> that builds a package from a set of
-    <emphasis>attributes</emphasis>.  A set is just a list of
-    key/value pairs where each key is a string and each value is an
-    arbitrary Nix expression.  They take the general form <literal>{
-    <replaceable>name1</replaceable> =
-    <replaceable>expr1</replaceable>; <replaceable>...</replaceable>
-    <replaceable>nameN</replaceable> =
-    <replaceable>exprN</replaceable>; }</literal>.</para>
-
-  </callout>
-
-  <callout arearefs='ex-hello-nix-co-3'>
-
-    <para>The attribute <varname>name</varname> specifies the symbolic
-    name and version of the package.  Nix doesn't really care about
-    these things, but they are used by for instance <command>nix-env
-    -q</command> to show a <quote>human-readable</quote> name for
-    packages.  This attribute is required by
-    <varname>mkDerivation</varname>.</para>
-
-  </callout>
-
-  <callout arearefs='ex-hello-nix-co-4'>
-
-    <para>The attribute <varname>builder</varname> specifies the
-    builder.  This attribute can sometimes be omitted, in which case
-    <varname>mkDerivation</varname> will fill in a default builder
-    (which does a <literal>configure; make; make install</literal>, in
-    essence).  Hello is sufficiently simple that the default builder
-    would suffice, but in this case, we will show an actual builder
-    for educational purposes.  The value
-    <command>./builder.sh</command> refers to the shell script shown
-    in <xref linkend='ex-hello-builder' />, discussed below.</para>
-
-  </callout>
-
-  <callout arearefs='ex-hello-nix-co-5'>
-
-    <para>The builder has to know what the sources of the package
-    are.  Here, the attribute <varname>src</varname> is bound to the
-    result of a call to the <command>fetchurl</command> function.
-    Given a URL and an MD5 hash of the expected contents of the file
-    at that URL, this function builds a derivation that downloads the
-    file and checks its hash.  So the sources are a dependency that
-    like all other dependencies is built before Hello itself is
-    built.</para>
-
-    <para>Instead of <varname>src</varname> any other name could have
-    been used, and in fact there can be any number of sources (bound
-    to different attributes).  However, <varname>src</varname> is
-    customary, and it's also expected by the default builder (which we
-    don't use in this example).</para>
-
-  </callout>
-
-  <callout arearefs='ex-hello-nix-co-6'>

-
-<para><xref linkend='ex-hello-builder' /> shows the builder referenced
-from Hello's Nix expression (stored in
-<filename>pkgs/applications/misc/hello/ex-1/builder.sh</filename>).
-The builder can actually be made a lot shorter by using the
-<emphasis>generic builder</emphasis> functions provided by
-<varname>stdenv</varname>, but here we write out the build steps to
-elucidate what a builder does.  It performs the following
-steps:</para>
-
-<calloutlist>
-
-  <callout arearefs='ex-hello-builder-co-1'>
-
-    <para>When Nix runs a builder, it initially completely clears the
-    environment (except for the attributes declared in the
-    derivation).  For instance, the <envar>PATH</envar> variable is
-    empty<footnote><para>Actually, it's initialised to
-    <filename>/path-not-set</filename> to prevent Bash from setting it
-    to a default value.</para></footnote>.  This is done to prevent
-    undeclared inputs from being used in the build process.  If for
-    example the <envar>PATH</envar> contained
-    <filename>/usr/bin</filename>, then you might accidentally use
-    <filename>/usr/bin/gcc</filename>.</para>
-
-    <para>So the first step is to set up the environment.  This is
-    done by calling the <filename>setup</filename> script of the
-    standard environment.  The environment variable
-    <envar>stdenv</envar> points to the location of the standard
-    environment being used.  (It wasn't specified explicitly as an
-    attribute in <xref linkend='ex-hello-nix' />, but
-    <varname>mkDerivation</varname> adds it automatically.)</para>
-
-  </callout>
-
-  <callout arearefs='ex-hello-builder-co-2'>
-
-    <para>Since Hello needs Perl, we have to make sure that Perl is in
-    the <envar>PATH</envar>.  The <envar>perl</envar> environment
-    variable points to the location of the Perl package (since it
-    was passed in as an attribute to the derivation), so
-    <filename><replaceable>$perl</replaceable>/bin</filename> is the
-    directory containing the Perl interpreter.</para>
-
-  </callout>
-
-  <callout arearefs='ex-hello-builder-co-3'>
-
-    <para>Now we have to unpack the sources.  The
-    <varname>src</varname> attribute was bound to the result of
-    fetching the Hello source tarball from the network, so the
-    <envar>src</envar> environment variable points to the location in
-    the Nix store to which the tarball was downloaded.  After
-    unpacking, we <command>cd</command> to the resulting source
-    directory.</para>
-
-    <para>The whole build is performed in a temporary directory
-    created in <varname>/tmp</varname>, by the way.  This directory is
-    removed after the builder finishes, so there is no need to clean
-    up the sources afterwards.  Also, the temporary directory is
-    always newly created, so you don't have to worry about files from
-    previous builds interfering with the current build.</para>
-
-  </callout>
-
-  <callout arearefs='ex-hello-builder-co-4'>
-
-    <para>GNU Hello is a typical Autoconf-based package, so we first
-    have to run its <filename>configure</filename> script.  In Nix
-    every package is stored in a separate location in the Nix store,
-    for instance
-    <filename>/nix/store/9a54ba97fb71b65fda531012d0443ce2-hello-2.1.1</filename>.
-    Nix computes this path by cryptographically hashing all attributes
-    of the derivation.  The path is passed to the builder through the
-    <envar>out</envar> environment variable.  So here we give
-    <filename>configure</filename> the parameter
-    <literal>--prefix=$out</literal> to cause Hello to be installed in
-    the expected location.</para>
-
-  </callout>
-
-  <callout arearefs='ex-hello-builder-co-5'>
-
-    <para>Finally we build Hello (<literal>make</literal>) and install
-    it into the location specified by <envar>out</envar>
-    (<literal>make install</literal>).</para>
-
-  </callout>
-
-</calloutlist>
-
-<para>If you are wondering about the absence of error checking on the
-result of various commands called in the builder: this is because the
-shell script is evaluated with Bash's <option>-e</option> option,
-which causes the script to be aborted if any command fails without an
-error check.</para>

-<section><title>Testing</title>
-
-<para>You can now try to build Hello.  Of course, you could do
-<literal>nix-env -f pkgs/top-level/all-packages.nix -i hello</literal>,
-but you may not want to install a possibly broken package just yet.
-The best way to test the package is by using the command <command
-linkend="sec-nix-build">nix-build</command>, which builds a Nix
-expression and creates a symlink named <filename>result</filename> in
-the current directory:
-
-<screen>
-$ nix-build pkgs/top-level/all-packages.nix -A hello
-building path `/nix/store/632d2b22514d...-hello-2.1.1'
-hello-2.1.1/
-hello-2.1.1/intl/
-hello-2.1.1/intl/ChangeLog
-<replaceable>...</replaceable>
-
-$ ls -l result
-lrwxrwxrwx ... 2006-09-29 10:43 result -> /nix/store/632d2b22514d...-hello-2.1.1
-
-$ ./result/bin/hello
-Hello, world!</screen>
-
-The <link linkend='opt-attr'><option>-A</option></link> option selects
-the <literal>hello</literal> attribute from
-<filename>all-packages.nix</filename>.  This is faster than using the
-symbolic package name specified by the <literal>name</literal>
-attribute (which also happens to be <literal>hello</literal>) and is
-unambiguous (there can be multiple packages with the symbolic name
-<literal>hello</literal>, but there can be only one attribute in a set
-named <literal>hello</literal>).</para>
-
-<para><command>nix-build</command> registers the
-<filename>./result</filename> symlink as a garbage collection root, so
-unless and until you delete the <filename>./result</filename> symlink,
-the output of the build will be safely kept on your system.  You can
-use <command>nix-build</command>’s <option
-linkend='opt-out-link'>-o</option> switch to give the symlink another
-name.</para>
-
-<para>Nix has a transactional semantics.  Once a build finishes
-successfully, Nix makes a note of this in its database: it registers
-that the path denoted by <envar>out</envar> is now
-<quote>valid</quote>.  If you try to build the derivation again, Nix
-will see that the path is already valid and finish immediately.  If a
-build fails, either because it returns a non-zero exit code, because
-Nix or the builder are killed, or because the machine crashes, then
-the output paths will not be registered as valid.  If you try to build
-the derivation again, Nix will remove the output paths if they exist
-(e.g., because the builder died half-way through <literal>make
-install</literal>) and try again.  Note that there is no
-<quote>negative caching</quote>: Nix doesn't remember that a build
-failed, and so a failed build can always be repeated.  This is because
-Nix cannot distinguish between permanent failures (e.g., a compiler
-error due to a syntax error in the source) and transient failures
-(e.g., a disk full condition).</para>
-
-<para>Nix also performs locking.  If you run multiple Nix builds
-simultaneously, and they try to build the same derivation, the first
-Nix instance that gets there will perform the build, while the others
-block (or perform other derivations if available) until the build
-finishes:
-
-<screen>
-$ nix-build pkgs/top-level/all-packages.nix -A hello
-waiting for lock on `/nix/store/0h5b7hp8d4hqfrw8igvx97x1xawrjnac-hello-2.1.1x'</screen>
-
-So it is always safe to run multiple instances of Nix in parallel
-(which isn’t the case with, say, <command>make</command>).</para>
-
-<para>If you have a system with multiple CPUs, you may want to have
-Nix build different derivations in parallel (insofar as possible).
-Just pass the option <link linkend='opt-max-jobs'><option>-j
-<replaceable>N</replaceable></option></link>, where
-<replaceable>N</replaceable> is the maximum number of jobs to be run
-in parallel, or set.  Typically this should be the number of
-CPUs.</para>

-looked something like this:
-
-<programlisting>
-PATH=$perl/bin:$PATH
-tar xvfz $src
-cd hello-*
-./configure --prefix=$out
-make
-make install</programlisting>
-
-The builders for almost all Unix packages look like this — set up some
-environment variables, unpack the sources, configure, build, and
-install.  For this reason the standard environment provides some Bash
-functions that automate the build process.  A builder using the
-generic build facilities in shown in <xref linkend='ex-hello-builder2'
-/>.</para>

-<section><title>The Nix expression language</title>
-
-<para>The Nix expression language is a pure, lazy, functional
-language.  Purity means that operations in the language don't have
-side-effects (for instance, there is no variable assignment).
-Laziness means that arguments to functions are evaluated only when
-they are needed.  Functional means that functions are
-<quote>normal</quote> values that can be passed around and manipulated
-in interesting ways.  The language is not a full-featured, general
-purpose language.  Its main job is to describe packages,
-compositions of packages, and the variability within
-packages.</para>
-
-<para>This section presents the various features of the
-language.</para>
-
-
-<section xml:id='ssec-values'><title>Values</title>
-
-
-<simplesect><title>Simple values</title>
-
-<para>Nix has the following basic data types:
-
-<itemizedlist>
-
-  <listitem>
-
-    <para><emphasis>Strings</emphasis> can be written in three
-    ways.</para>
-
-    <para>The most common way is to enclose the string between double
-    quotes, e.g., <literal>"foo bar"</literal>.  Strings can span
-    multiple lines.  The special characters <literal>"</literal> and
-    <literal>\</literal> and the character sequence
-    <literal>${</literal> must be escaped by prefixing them with a
-    backslash (<literal>\</literal>).  Newlines, carriage returns and
-    tabs can be written as <literal>\n</literal>,
-    <literal>\r</literal> and <literal>\t</literal>,
-    respectively.</para>
-
-    <para>You can include the result of an expression into a string by
-    enclosing it in
-    <literal>${<replaceable>...</replaceable>}</literal>, a feature
-    known as <emphasis>antiquotation</emphasis>.  The enclosed
-    expression must evaluate to something that can be coerced into a
-    string (meaning that it must be a string, a path, or a
-    derivation).  For instance, rather than writing
-
-<programlisting>
-"--with-freetype2-library=" + freetype + "/lib"</programlisting>
-
-    (where <varname>freetype</varname> is a derivation), you can
-    instead write the more natural
-
-<programlisting>
-"--with-freetype2-library=${freetype}/lib"</programlisting>
-
-    The latter is automatically translated to the former.  A more
-    complicated example (from the Nix expression for <link
-    xlink:href='http://www.trolltech.com/products/qt'>Qt</link>):
-
-<programlisting>
-configureFlags = "
-  -system-zlib -system-libpng -system-libjpeg
-  ${if openglSupport then "-dlopen-opengl
-    -L${mesa}/lib -I${mesa}/include
-    -L${libXmu}/lib -I${libXmu}/include" else ""}
-  ${if threadSupport then "-thread" else "-no-thread"}
-";</programlisting>
-
-    Note that Nix expressions and strings can be arbitrarily nested;
-    in this case the outer string contains various antiquotations that
-    themselves contain strings (e.g., <literal>"-thread"</literal>),
-    some of which in turn contain expressions (e.g.,
-    <literal>${mesa}</literal>).</para>
-
-    <para>The second way to write string literals is as an
-    <emphasis>indented string</emphasis>, which is enclosed between
-    pairs of <emphasis>double single-quotes</emphasis>, like so:
-
-<programlisting>
-''
-  This is the first line.
-  This is the second line.
-    This is the third line.
-''</programlisting>
-
-    This kind of string literal intelligently strips indentation from
-    the start of each line.  To be precise, it strips from each line a
-    number of spaces equal to the minimal indentation of the string as
-    a whole (disregarding the indentation of empty lines).  For
-    instance, the first and second line are indented two space, while
-    the third line is indented four spaces.  Thus, two spaces are
-    stripped from each line, so the resulting string is
-
-<programlisting>
-"This is the first line.\nThis is the second line.\n  This is the third line.\n"</programlisting>
-
-    </para>
-
-    <para>Note that the whitespace and newline following the opening
-    <literal>''</literal> is ignored if there is no non-whitespace
-    text on the initial line.</para>
-
-    <para>Antiquotation
-    (<literal>${<replaceable>expr</replaceable>}</literal>) is
-    supported in indented strings.</para>
-
-    <para>Since <literal>${</literal> and <literal>''</literal> have
-    special meaning in indented strings, you need a way to quote them.
-    <literal>${</literal> can be escaped by prefixing it with
-    <literal>''</literal> (that is, two single quotes), i.e.,
-    <literal>''${</literal>.  <literal>''</literal> can be escaped by
-    prefixing it with <literal>'</literal>, i.e.,
-    <literal>'''</literal>.  Finally, linefeed, carriage-return and
-    tab characters can be written as <literal>''\n</literal>,
-    <literal>''\r</literal>, <literal>''\t</literal>.</para>
-
-    <para>Indented strings are primarily useful in that they allow
-    multi-line string literals to follow the indentation of the
-    enclosing Nix expression, and that less escaping is typically
-    necessary for strings representing languages such as shell scripts
-    and configuration files because <literal>''</literal> is much less
-    common than <literal>"</literal>.  Example:
-
-<programlisting>
-stdenv.mkDerivation {
-  <replaceable>...</replaceable>
-  postInstall =
-    ''
-      mkdir $out/bin $out/etc
-      cp foo $out/bin
-      echo "Hello World" > $out/etc/foo.conf
-      ${if enableBar then "cp bar $out/bin" else ""}
-    '';
-  <replaceable>...</replaceable>
-}
-</programlisting>
-
-    </para>
-
-    <para>Finally, as a convenience, <emphasis>URIs</emphasis> as
-    defined in appendix B of <link
-    xlink:href='http://www.ietf.org/rfc/rfc2396.txt'>RFC 2396</link>
-    can be written <emphasis>as is</emphasis>, without quotes.  For
-    instance, the string
-    <literal>"http://example.org/foo.tar.bz2"</literal>
-    can also be written as
-    <literal>http://example.org/foo.tar.bz2</literal>.</para>

-<simplesect><title>Lists</title>
-
-<para>Lists are formed by enclosing a whitespace-separated list of
-values between square brackets.  For example,
-
-<programlisting>
-[ 123 ./foo.nix "abc" (f { x = y; }) ]</programlisting>
-
-defines a list of four elements, the last being the result of a call
-to the function <varname>f</varname>.  Note that function calls have
-to be enclosed in parentheses.  If they had been omitted, e.g.,
-
-<programlisting>
-[ 123 ./foo.nix "abc" f { x = y; } ]</programlisting>
-
-the result would be a list of five elements, the fourth one being a
-function and the fifth being a set.</para>
-
-</simplesect>
-
-
-<simplesect><title>Sets</title>
-
-<para>Sets are really the core of the language, since ultimately the
-Nix language is all about creating derivations, which are really just
-sets of attributes to be passed to build scripts.</para>
-
-<para>Sets are just a list of name/value pairs (called
-<emphasis>attributes</emphasis>) enclosed in curly brackets, where
-each value is an arbitrary expression terminated by a semicolon.  For
-example:
-
-<programlisting>
-{ x = 123;
-  text = "Hello";
-  y = f { bla = 456; };
-}</programlisting>
-
-This defines a set with attributes named <varname>x</varname>,
-<varname>text</varname>, <varname>y</varname>.  The order of the
-attributes is irrelevant.  An attribute name may only occur
-once.</para>
-
-<para>Attributes can be selected from a set using the
-<literal>.</literal> operator.  For instance,
-
-<programlisting>
-{ a = "Foo"; b = "Bar"; }.a</programlisting>
-
-evaluates to <literal>"Foo"</literal>.  It is possible to provide a
-default value in an attribute selection using the
-<literal>or</literal> keyword.  For example,
-
-<programlisting>
-{ a = "Foo"; b = "Bar"; }.c or "Xyzzy"</programlisting>
-
-will evaluate to <literal>"Xyzzy"</literal> because there is no
-<varname>c</varname> attribute in the set.</para>
-
-<para>You can use arbitrary double-quoted strings as attribute
-names:
-
-<programlisting>
-{ "foo ${bar}" = 123; "nix-1.0" = 456; }."foo ${bar}"
-</programlisting>
-
-This will evaluate to <literal>123</literal> (Assuming
-<literal>bar</literal> is antiquotable). In the case where an
-attribute name is just a single antiquotation, the quotes can be
-dropped:
-
-<programlisting>
-{ foo = 123; }.${bar} or 456 </programlisting>
-
-This will evaluate to <literal>123</literal> if
-<literal>bar</literal> evaluates to <literal>"foo"</literal> when
-coerced to a string and <literal>456</literal> otherwise (again
-assuming <literal>bar</literal> is antiquotable).</para>
-
-<para>In the special case where an attribute name inside of a set declaration
-evaluates to <literal>null</literal> (which is normally an error, as
-<literal>null</literal> is not antiquotable), that attribute is simply not
-added to the set:
-
-<programlisting>
-{ ${if foo then "bar" else null} = true; }</programlisting>
-
-This will evaluate to <literal>{}</literal> if <literal>foo</literal>
-evaluates to <literal>false</literal>.</para>

-<simplesect><title>Recursive sets</title>
-
-<para>Recursive sets are just normal sets, but the attributes can
-refer to each other.  For example,
-
-<programlisting>
-rec {
-  x = y;
-  y = 123;
-}.x
-</programlisting>
-
-evaluates to <literal>123</literal>.  Note that without
-<literal>rec</literal> the binding <literal>x = y;</literal> would
-refer to the variable <varname>y</varname> in the surrounding scope,
-if one exists, and would be invalid if no such variable exists.  That
-is, in a normal (non-recursive) set, attributes are not added to the
-lexical scope; in a recursive set, they are.</para>
-
-<para>Recursive sets of course introduce the danger of infinite
-recursion.  For example,
-
-<programlisting>
-rec {
-  x = y;
-  y = x;
-}.x</programlisting>
-
-does not terminate<footnote><para>Actually, Nix detects infinite

-<simplesect><title>Let-expressions</title>
-
-<para>A let-expression allows you define local variables for an
-expression.  For instance,
-
-<programlisting>
-let
-  x = "foo";
-  y = "bar";
-in x + y</programlisting>
-
-evaluates to <literal>"foobar"</literal>.

-
-
-<simplesect><title>Inheriting attributes</title>
-
-<para>When defining a set it is often convenient to copy variables
-from the surrounding lexical scope (e.g., when you want to propagate
-attributes).  This can be shortened using the
-<literal>inherit</literal> keyword.  For instance,
-
-<programlisting>
-let x = 123; in
-{ inherit x;
-  y = 456;
-}</programlisting>
-
-evaluates to <literal>{ x = 123; y = 456; }</literal>.  (Note that
-this works because <varname>x</varname> is added to the lexical scope
-by the <literal>let</literal> construct.)  It is also possible to
-inherit attributes from another set.  For instance, in this fragment
-from <filename>all-packages.nix</filename>,
-
-<programlisting>
-  graphviz = (import ../tools/graphics/graphviz) {
-    inherit fetchurl stdenv libpng libjpeg expat x11 yacc;
-    inherit (xlibs) libXaw;
-  };
-
-  xlibs = {
-    libX11 = ...;
-    libXaw = ...;
-    ...
-  }
-
-  libpng = ...;
-  libjpg = ...;
-  ...</programlisting>
-
-the set used in the function call to the function defined in
-<filename>../tools/graphics/graphviz</filename> inherits a number of
-variables from the surrounding scope (<varname>fetchurl</varname>
-... <varname>yacc</varname>), but also inherits
-<varname>libXaw</varname> (the X Athena Widgets) from the
-<varname>xlibs</varname> (X11 client-side libraries) set.</para>

-
-<para>Functions have the following form:
-
-<programlisting>
-<replaceable>pattern</replaceable>: <replaceable>body</replaceable></programlisting>
-
-The pattern specifies what the argument of the function must look
-like, and binds variables in the body to (parts of) the
-argument.  There are three kinds of patterns:</para>
-
-<itemizedlist>
-
-
-  <listitem><para>If a pattern is a single identifier, then the

-
-  <programlisting>
-let negate = x: !x;
-    concat = x: y: x + y;
-in if negate true then concat "foo" "bar" else ""</programlisting>
-
-  Note that <function>concat</function> is a function that takes one
-  argument and returns a function that takes another argument.  This
-  allows partial parameterisation (i.e., only filling some of the
-  arguments of a function); e.g.,
-
-  <programlisting>
-map (concat "foo") [ "bar" "bla" "abc" ]</programlisting>
-
-  evaluates to <literal>[ "foobar" "foobla"
-  "fooabc" ]</literal>.</para></listitem>
-
-
-  <listitem><para>A <emphasis>set pattern</emphasis> of the form
-  <literal>{ name1, name2, …, nameN }</literal> matches a set
-  containing the listed attributes, and binds the values of those
-  attributes to variables in the function body.  For example, the
-  function
-
-<programlisting>
-{ x, y, z }: z + y + x</programlisting>
-
-  can only be called with a set containing exactly the attributes
-  <varname>x</varname>, <varname>y</varname> and

-  for attributes, in which case they are allowed to be missing.  A

-  <replaceable>e</replaceable> is an arbitrary expression.  For example,
-
-<programlisting>
-{ x, y ? "foo", z ? "bar" }: z + y + x</programlisting>
-
-  specifies a function that only requires an attribute named

-
-
-  <listitem><para>An <literal>@</literal>-pattern requires that the

-<calloutlist>
-
-  <callout arearefs='ex-subversion-nix-co-1'>
-    <para>This assertion states that if Subversion is to have support
-    for local repositories, then Berkeley DB is needed.  So if the
-    Subversion function is called with the
-    <varname>localServer</varname> argument set to
-    <literal>true</literal> but the <varname>db4</varname> argument
-    set to <literal>null</literal>, then the evaluation fails.</para>
-  </callout>
-
-  <callout arearefs='ex-subversion-nix-co-2'>
-    <para>This is a more subtle condition: if Subversion is built with
-    Apache (<literal>httpServer</literal>) support, then the Expat
-    library (an XML library) used by Subversion should be same as the
-    one used by Apache.  This is because in this configuration
-    Subversion code ends up being linked with Apache code, and if the

-    <para>This assertion says that in order for Subversion to have SSL

-
-
-  <varlistentry><term><varname>exportReferencesGraph</varname></term>
-
-    <listitem><para>This attribute allows builders access to the
-    references graph of their inputs.  The attribute is a list of
-    inputs in the Nix store whose references graph the builder needs
-    to know.  The value of this attribute should be a list of pairs
-    <literal>[ <replaceable>name1</replaceable>

-    The text files have the format used by <command>nix-store

-
-<programlisting>
-derivation {

-    <term><varname>outputHashAlgo</varname></term>
-    <term><varname>outputHashMode</varname></term>
-
-    <listitem><para>These attributes declare that the derivation is a
-    so-called <emphasis>fixed-output derivation</emphasis>, which
-    means that a cryptographic hash of the output is already known in
-    advance.  When the build of a fixed-output derivation finishes,
-    Nix computes the cryptographic hash of the output and compares it
-    to the hash declared with these attributes.  If there is a
-    mismatch, the build fails.</para>
-
-    <para>The rationale for fixed-output derivations is derivations
-    such as those produced by the <function>fetchurl</function>
-    function.  This function downloads a file from a given URL.  To
-    ensure that the downloaded file has not been modified, the caller
-    must also specify a cryptographic hash of the file.  For example,
-
-<programlisting>
-fetchurl {
-  url = http://ftp.gnu.org/pub/gnu/hello/hello-2.1.1.tar.gz;
-  md5 = "70c9ccf9fac07f762c24f2df2290784d";
-}
-</programlisting>
-
-    It sometimes happens that the URL of the file changes, e.g.,
-    because servers are reorganised or no longer available.  We then
-    must update the call to <function>fetchurl</function>, e.g.,
-
-<programlisting>
-fetchurl {
-  url = ftp://ftp.nluug.nl/pub/gnu/hello/hello-2.1.1.tar.gz;
-  md5 = "70c9ccf9fac07f762c24f2df2290784d";
-}
-</programlisting>
-
-    If a <function>fetchurl</function> derivation was treated like a
-    normal derivation, the output paths of the derivation and
-    <emphasis>all derivations depending on it</emphasis> would change.
-    For instance, if we were to change the URL of the Glibc source
-    distribution in Nixpkgs (a package on which almost all other
-    packages depend) massive rebuilds would be needed.  This is
-    unfortunate for a change which we know cannot have a real effect
-    as it propagates upwards through the dependency graph.</para>
-
-    <para>For fixed-output derivations, on the other hand, the name of
-    the output path only depends on the <varname>outputHash*</varname>
-    and <varname>name</varname> attributes, while all other attributes
-    are ignored for the purpose of computing the output path.  (The
-    <varname>name</varname> attribute is included because it is part
-    of the path.)</para>
-
-    <para>As an example, here is the (simplified) Nix expression for
-    <varname>fetchurl</varname>:
-
-<programlisting>
-{ stdenv, curl }: # The <command>curl</command> program is used for downloading.
-
-{ url, md5 }:
-
-stdenv.mkDerivation {
-  name = baseNameOf (toString url);
-  builder = ./builder.sh;
-  buildInputs = [ curl ];
-
-  # This is a fixed-output derivation; the output must be a regular
-  # file with MD5 hash <varname>md5</varname>.
-  outputHashMode = "flat";
-  outputHashAlgo = "md5";
-  outputHash = md5;
-
-  inherit url;
-}
-</programlisting>
-
-    </para>
-
-    <para>The <varname>outputHashAlgo</varname> attribute specifies
-    the hash algorithm used to compute the hash.  It can currently be
-    <literal>"md5"</literal>, <literal>"sha1"</literal> or
-    <literal>"sha256"</literal>.</para>
-
-    <para>The <varname>outputHashMode</varname> attribute determines

-Nix is a purely functional package manager. It allows multiple
-versions of a package to be installed side-by-side, ensures that
-dependency specifications are complete, supports atomic upgrades and
-rollbacks, allows non-root users to install software, and has many
-other features. It is the basis of the NixOS Linux distribution, but
-it can be used equally well under other Unix systems.

-# General operation:

-# Try to find a free machine of type $neededSystem.  We do this as

-# - We acquire an exclusive lock on $currentLoad/main-lock.
-# - For each machine $machine of type $neededSystem and for each $slot
-#   less than the maximum load for that machine, we try to get an
-#   exclusive lock on $currentLoad/$machine-$slot (without blocking).
-#   If we get such a lock, we send "accept" to the caller.  Otherwise,

-# - We release the exclusive lock on $currentLoad/main-lock.
-# - We perform the build on $neededSystem.
-# - We release the exclusive lock on $currentLoad/$machine-$slot.

-# The nice thing about this scheme is that if we die prematurely, the

-.Nd generate a patch between two binary files
-.Sh SYNOPSIS
-.Nm
-.Ao Ar oldfile Ac Ao Ar newfile Ac Ao Ar patchfile Ac
-.Sh DESCRIPTION
-.Nm
-compares
-.Ao Ar oldfile Ac
-to
-.Ao Ar newfile Ac
-and writes to
-.Ao Ar patchfile Ac
-a binary patch suitable for use by bspatch(1).
-When
-.Ao Ar oldfile Ac
-and
-.Ao Ar newfile Ac
-are two versions of an executable program, the
-patches produced are on average a factor of five smaller
-than those produced by any other binary patch tool known
-to the author.
-.Pp
-.Nm
-uses memory equal to 17 times the size of 
-.Ao Ar oldfile Ac ,
-and requires
-an absolute minimum working set size of 8 times the size of oldfile.
