# Cies Breijs' Oh-my-zsh theme
# 
# Typical prompt is 3 lines; a blank line, a status line and the actual prompt.
# Features:
#  * no right aligning anything, everything to the left
#  * username, full hostname, full path, rvm, git (optional), full date
#  * continuation prompt
#  * non zero return values are shown
#
# TODO:
#  * hashmap hostnames to a list of readable fg/bg color combinations, for an 
#         automated yet deterministic color coding for each hostname
