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

   8 # NOTE Use with care!  "RC" should only follow x.x.x, with
   9 # vendor tags after that.  Be traditional; avoid "rc0".
  10
  11 # NOTE:  This *ONLY* updates the "configure.ac" version tag.
  12 # It does not affect GIT tags.  Use this script immediately
  13 # before making a release, to remove the "-dev" tag and to
  14 # update the version label.  Then commit the change and tag
  15 # that commit to match the version label.
