# In a git/autoconf/automake-enabled project with a NEWS file and a version-
# controlled .prev-version file, automate the procedure by which we record
# the date, release-type and version string in the NEWS file. That commit
# will serve to identify the release, so apply a signed tag to it as well.

Usage: $ME [OPTION...] VERSION RELEASE_TYPE
Run this script from top_srcdir to perform the final pre-release NEWS
update in which the date, release-type and version string are
recorded. Commit that result with a log entry marking the release,
and apply a signed tag. Run it from your project's top-level
directory.
Requirements:
- you use git for version-control
- a version-controlled .prev-version file
- a NEWS file, with line 3 identical to this:
$noteworthy_stub
Options:
--branch=BRANCH set release branch (default: $branch)
-C, --builddir=DIR location of (configured) Makefile (default: $builddir)
--help print this help, then exit
--version print version number, then exit
EXAMPLE:
To update NEWS and tag the beta 8.1 release of coreutils, I would run this:
$ME 8.1 beta
Report bugs and patches to <bug-gnulib@gnu.org>.
