# This theme was obviously inspired a lot by
#
# - Demula theme
#
# which in itself was inspired by :
#
# - Ronacher's dotfiles (mitsuhikos) - http://github.com/mitsuhiko/dotfiles/tree/master/bash/
# - Glenbot - http://theglenbot.com/custom-bash-shell-for-development/
# - My extravagant zsh - http://stevelosh.com/blog/2010/02/my-extravagant-zsh-prompt/
# - Monokai colors - http://monokai.nl/blog/2006/07/15/textmate-color-theme/
# - Bash_it modern theme
#
# Hawaii50 theme supports :
#
# - configurable directory length
# - hg, svn, git detection (I work in all of them)
# - virtualenv, rvm + gemsets
