# This hook script will automatically add the Pivotal Tracker ID
# to the beginning of the git commit message (in the format of
# [#12345678]) if it is not already there.
#
# The script pulls the ID from the beginning of the branch name.  If
# the branch name does not start with the Pivotal Tracker ID, then
# this script will do nothing.
#
# Specifying the Pivotal Tracker ID in the git commit message allows
# Pivotal to list all commits associated with a story when the
# story is viewed.
#
# To enable this script, copy it into your repo's .git/hooks directory.
