gitcommit

#!/usr/bin/env ruby
# A wrapper around "git commit" that provides a template message
# conforming to RentPath conventions.

# inspired by Zander Hill's vim macro (https://gist.github.com/anonymous/b6cf9e57c9bb26cf3f3f)
# Assumes branches are named with the following components separated
# by underscores:
# 1. developer initials (one or more of these components are allowed)
# 2. story number
# 3. free text description (optional; may contain underscores)
# Examples:
# "sb_12345_fix_serious_bug"
# "sb_zh_67890" (two devs, no optional description)
