crunch.zsh-theme

# CRUNCH - created from Steve Eley's cat waxing.
# Initially hacked from the Dallas theme. Thanks, Dallas Reedy.
#
# This theme assumes you do most of your oh-my-zsh'ed "colorful" work at a single machine, 
# and eschews the standard space-consuming user and hostname info.  Instead, only the 
# things that vary in my own workflow are shown:
#
# * The time (not the date)
# * The RVM version and gemset (omitting the 'ruby' name if it's MRI)
# * The current directory
# * The Git branch and its 'dirty' state
# 
# Colors are at the top so you can mess with those separately if you like.
# For the most part I stuck with Dallas's.
