# Git commit-msg hook adapted from Henrik Nyh's <http://henrik.nyh.se> original version
# <https://gist.github.com/184711>
#
# Works in tandem with the redmine_stagecoach gem to automatically add your
# branch's associated github issue number to your commit message.
#
# If you include "#noref" in the commit message, nothing will be added to
# the commit message, and the "#noref" itself will be stripped.
#
# If you want to close the issue with this commit, include "#close" in your commit message
#
# Install:
#
# cd your_project
# stick it in .git/hooks/commit-msg
# chmod u+x .git/hooks/commit-msg

# Find the stagecoach gem path.  The gsub just trims /bin/stagecoach off the end.
