{# This document uses jinja2 templating markup.  Please refer to the Jinja2
   template documentation for further information.

   This file contains jinja2 macros that are used by the README.textile file to
   differentiate between, and generate, textile and plaintext output.

   We can use indenting because we set lstrip_blocks=True when we setup the
   jinja2 environment in the python scripts that process this file. #}.
