bullet-train.zsh-theme

# README
#
# In order for this theme to render correctly, you will need a
# [Powerline-patched font](https://github.com/Lokaltog/powerline-fonts).
#
# In addition, I recommend the
# [Tomorrow Night theme](https://github.com/chriskempson/tomorrow-theme) and, if
# you're using it on Mac OS X, [iTerm 2](http://www.iterm2.com/) over
# Terminal.app - it has significantly better color fidelity.
