#
# Ciacho Theme 
# Based on agnoster theme
# In order for this theme to render correctly, you will need a
# [Powerline-patched font](https://github.com/Lokaltog/powerline-fonts).
# Make sure you have a recent version: the code points that Powerline
# uses changed in 2012, and older versions will display incorrectly,
# in confusing ways.
