# Sample Pit integration hook.
#
# 1. Appends Pit task number to the commit message when you use
#    task number as part of your Git branch name. Specifically,
#    leading or trailing digits of the branch name are treated
#    as Pit task number.
#
# 2. Lets you specify task status and updates it in Pit accordingly.
#
# 3. Creates task note with the complete commit massage.
#
# Drop into .git/hooks/commit-msg
# chmod +x .git/hooks/commit-msg
