# Determines the "branch" of the current repo and emits it.
# For use in generating the prompt.
# This is portable to both zsh and bash and works in both
# git and mercurial repos and aims to avoid invoking the
# command line utilities for speed of prompt updates

# To use from zsh:
#  NOTE! the single quotes are important; if you use double quotes
#  then the prompt won't change when you chdir or checkout different
#  branches!
