    "Many computer users need to manipulate text files: extract and then
operate on data from parts of certain lines while discarding the rest, make
changes in various text files wherever certain patterns appear, and so on.
To write a program to do these things in a language such as C or Pascal is a
time-consuming inconvenience that may take many lines of code.  The job is
easy with awk, especially the GNU implementation: Gawk.

The awk utility interprets a special-purpose programming language that makes
it possible to handle many data-reformatting jobs with just a few lines of
code.")

   (description
    "GNU Diffutils is a package of several programs related to finding
differences between files.

Computer users often find occasion to ask how two files differ. Perhaps one
file is a newer version of the other file. Or maybe the two files started out
as identical copies but were changed by different people.

You can use the diff command to show differences between two files, or each
corresponding file in two directories. diff outputs differences between files
line by line in any of several formats, selectable by command line
options. This set of differences is often called a ‘diff’ or ‘patch’. For
files that are identical, diff normally produces no output; for
binary (non-text) files, diff normally reports only that they are different.

You can use the cmp command to show the offsets and line numbers where two
files differ. cmp can also show all the characters that differ between the
two files, side by side.

You can use the diff3 command to show differences among three files. When two
people have made independent changes to a common original, diff3 can report
the differences between the original and the two changed versions, and can
produce a merged file that contains both persons' changes together with
warnings about conflicts.

You can use the sdiff command to merge two files interactively.")

functions have a regular interface.

The main target applications for GMP are cryptography applications and
research, Internet security applications, algebra systems, computational
algebra research, etc.

GMP is carefully designed to be as fast as possible, both for small operands
and for huge operands.  The speed is achieved by using fullwords as the basic
arithmetic type, by using fast algorithms, with highly optimised assembly
code for the most common inner loops for a lot of CPUs, and by a general
emphasis on speed.

GMP is faster than any other bignum library.  The advantage for GMP increases
with the operand sizes for many operations, since GMP uses asymptotically
faster algorithms.")

to various calling conventions.  This allows a programmer to call any
function specified by a call interface description at run-time.

FFI stands for Foreign Function Interface.  A foreign function interface is
the popular name for the interface that allows code written in one language
to call code written in another language.  The libffi library really only
provides the lowest, machine dependent layer of a fully featured foreign
function interface.  A layer must exist above libffi that handles type
conversions for values passed between the two languages.")

    "The Boehm-Demers-Weiser conservative garbage collector can be used
as a garbage collecting replacement for C malloc or C++ new.  It allows
you to allocate memory basically as you normally would, without
explicitly deallocating memory that is no longer useful.  The collector
automatically recycles memory when it determines that it can no longer
be otherwise accessed.

The collector is also used by a number of programming language
implementations that either use C as intermediate code, want to
facilitate easier interoperation with C libraries, or just prefer the
simple collector interface.

Alternatively, the garbage collector may be used as a leak detector for
C or C++ programs, though that is not its primary goal.")
