# Adds the current branch to the bash prompt when the working directory is
# part of a Git repository. Includes color-coding and indicators to quickly
# indicate the status of working directory.
#
# To use: Copy into ~/.bashrc and tweak if desired.
#
# Based upon the following gists:
# <https://gist.github.com/henrik/31631>
# <https://gist.github.com/srguiwiz/de87bf6355717f0eede5>
# Modified by me, using ideas from comments on those gists.
#
# License: MIT, unless the authors of those two gists object :)
