DESCRIPTION="Gnulib is a library of common routines intended to be shared at the source level"
HOMEPAGE="http://www.gnu.org/software/gnulib"

# This tar.gz is created on-the-fly when downloaded from
# http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=snapshot;h=${GNULIB_COMMIT_GITID};sf=tgz
# So to have persistent checksums, we need to download once and cache it.
#
# To get a new version, download a "snapshot" from
# http://git.savannah.gnu.org/gitweb/?p=gnulib.git
# take the commit-id as GNULIB_COMMIT_GITID
# and the committer's timestamp (not the author's one), year to second, UTC
# as the ebuild version.
#
# To see what the last commit message for the current version was, use
# http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=commit;h=${GNULIB_COMMIT_GITID}
