+decompression to standard output.
+
+What makes this special is that Bootar is distributed as a
+self-extracting Scheme (SES) program.  That is, a little script that
+outputs the source code of Bootar.  This makes it possible to go from
+pure Scheme to Tar and decompression in one easy step.")

-;;; Commentary:
-;;;
-;;; This is a wrapper for the linker.  Its purpose is to inspect the -L and
-;;; -l switches passed to the linker, add corresponding -rpath arguments, and
-;;; invoke the actual linker with this new set of arguments.
-;;;
-;;; The alternatives to this hack would be:
-;;;
-;;;   1. Using $LD_RUN_PATH.  However, that would tend to include more than
-;;;      needed in the RPATH; for instance, given a package with `libfoo' as
-;;;      an input, all its binaries would have libfoo in their RPATH,
-;;;      regardless of whether they actually NEED it.
-;;;
-;;;   2. Use a GCC "lib" spec string such as `%{L*:-rpath %*}', which adds a
-;;;      `-rpath LIBDIR' argument for each occurrence of `-L LIBDIR'.
-;;;      However, this doesn't work when $LIBRARY_PATH is used, because the
-;;;      additional `-L' switches are not matched by the above rule, because
-;;;      the rule only matches explicit user-provided switches.  See
-;;;      <http://gcc.gnu.org/ml/gcc-help/2012-09/msg00110.html> for details.
-;;;
-;;; As a bonus, this wrapper checks for "impurities"--i.e., references to
-;;; libraries outside the store.

+Make libcurl respect the SSL_CERT_{DIR,FILE} variables by default. The variables
+are fetched during initialization to preserve thread-safety (curl_global_init(3)
+must be called when no other threads exist).

-
-* src/Makefile.am: Use pkg_namespace (instead of namespace).
-* src/mkerrnos.awk: Likewise.
-* lang/cl/mkerrcodes.awk: Don't escape # in regexp.
-* src/mkerrcodes.awk, src/mkerrcodes1.awk, src/mkerrcodes2.awk: Ditto.

-
-In Gawk 5.0, regexp routines are replaced by Gnulib implementation,
-which only allows escaping specific characters.

-This patch adds support for newer versions of Poppler and some upstream
-TexLive fixes, including one for CVE-2018-17407.
-
-It is taken from Linux From Scratch:
-<http://www.linuxfromscratch.org/patches/blfs/svn/texlive-20180414-source-upstream_fixes-3.patch>.
-
-Submitted By: Ken Moffat <ken at linuxfromscratch dot org>
-Date: 2018-12-26
-Initial Package Version: 20180414
-Upstream Status: Applied
-Origin: Upstream
-Description: Two fixes, cherry-picked from svn plus a CVE fix.
-I have removed the partial fixes for various system versions of poppler.
-
-r47469 Fix segfault in dvipdfm-x (XeTeX) on 1/2/4-bit transparent indexed PNGs.
-
-r47477 Fix a ptex regression for discontinuous kinsoku table.
-
-Also, via fedora (I got lost in svn) a critical fix for CVE-2018-17407
-
-"A buffer overflow in the handling of Type 1 fonts allows arbitrary code
-execution when a malicious font is loaded by one of the vulnerable tools:
-pdflatex, pdftex, dvips, or luatex."
