    # agnoster's Theme - https://gist.github.com/3712874
    # A Powerline-inspired theme for ZSH
    #
    # # README
    #
    # In order for this theme to render correctly, you will need a
    # [Powerline-patched font](https://gist.github.com/1595572).
    #
    # In addition, I recommend the
    # [Solarized theme](https://github.com/altercation/solarized/) 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.
    #
    # # Goals
    #
    # The aim of this theme is to only show you *relevant* information. Like most
    # prompts, it will only show git information when in a git working directory.
    # However, it goes a step further: everything from the current user and
    # hostname to whether the last call exited with an error to whether background
    # jobs are running in this shell will all be displayed automatically when
    # appropriate.
