# Usage: unlocktree [-f]
#
# Unlocks the Postgres source tree.  This script will also create a checkin
# file, which is useful for mailing out to the post_hackers.  It also updates
# the checkin log.
#
# When used with the "-f" option, unlocktree will break another user's tree
# lock.  The lock breaker will be prompted for mail to explain why the tree
# lock was broken.
