# GCC release generation script.
#
# Originally written by Jeff Law <law@redhat.com>.

# We need separate variables for the tag in the CVS sources and the
# name of the release directory.  Consider if we have a packaging problem
# and need to respin the release.  The sources do not change, but the release
# name changes.
#
# [[ Not clear.  You  can purge the old tag and make a new one, too.
#    That way they continue to match.  Maximize consistency. ]]
#
# We used to use a tag to get the previous release, but it is more reliable to
# actually unpack the previous release from the ftp directory.  Consider files
# like .brik which are in the release, but not in the repository.
