+# 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://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.
+#
+# In addition, I recommend the
+# [Solarized theme](https://github.com/altercation/solarized/) and, if you're
+# using it on Mac OS X, [iTerm 2](https://iterm2.com/) over Terminal.app -
+# it has significantly better color fidelity.
+#
+# If using with "light" variant of the Solarized color schema, set
+# SOLARIZED_THEME variable to "light". If you don't specify, we'll assume
+# you're using the "dark" variant.
+#
+# # 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.
+
+### Segment drawing
+# A few utility functions to make it easy and re-usable to draw segmented prompts

+  # If this is not working for you, you probably have an old version of the
+  # Powerline-patched fonts installed. Download and install the new version.
+  # Do not submit PRs to change this unless you have reviewed the Powerline code point
+  # history and have new information.
