# Release under the GNU GPL v2 (or later versions).

# FIXME Remove more bash-isms.  Fix errors making "ash -e" lose.

# NOTE Use with care!  "RC" should only follow x.x.x, with
# vendor tags after that.  Be traditional; avoid "rc0".

# NOTE:  This *ONLY* updates the "configure.ac" version tag.
# It does not affect GIT tags.  Use this script immediately
# before making a release, to remove the "-dev" tag and to
# update the version label.  Then commit the change and tag
# that commit to match the version label.

  bump tag <label>             Add or bump a versioned tag (e.g. -rcN).
