# Here is an example usage of this script, to create a GCC 3.0.2
# prerelease:
#
#   gcc_release -r 3.0.2
#
# This script will automatically use the head of the release branch
# to generate the release.

  -s name:cvsbranch    Create a snapshot, not a real release.

  -d destination       Local working directory where we will build the release
                       (default=${HOME}).
  -f                   Create a final release (and update ChangeLogs,...).
  -l                   Indicate that we are running on gcc.gnu.org.
  -p previous-tarball  Location of a previous tarball (to generate diff files).
  -t tag               Tag to mark the release in CVS.
  -u username          Username for upload operations.
