+#
+# 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
+#
+# Screenshot:

+#
+# And yes, we code out in Hawaii. :D
+#
+# Note: I also am really new to this bash scripting game, so if you see things
+# that are flat out wrong, or if you think of something neat, just send a pull
+# request. This probably only works on a Mac - as some functions are OS
+# specific like getting ip, etc.
