My pretty prompt!

.bash_prompt

#!/bin/bash
#
# DESCRIPTION:
#
#   Set the bash prompt according to:
#    * the active virtualenv
#    * the branch of the current git/mercurial repository
#    * the return value of the previous command
#    * the fact you just came from Windows and are used to having newlines in
#      your prompts.
#
# USAGE:
#
#   1. Save this file as ~/.bash_prompt
#   2. Add the following line to the end of your ~/.bashrc or ~/.bash_profile:
#        . ~/.bash_prompt
#
# LINEAGE:
#   Based on work by Laila Atrmouh and Jaques-Olivier Dordonne
#   Based on work by woods - https://gist.github.com/31967

# The various escape codes that we can use to color our prompt.
