github_asciidoc.py
------------------
This is a wrapper file for parsing AsciiDoc files at github. It wraps the
current AsciiDoc API.
AsciiDoc specifications suggest using the file extension of `.txt` however this
causes conflict because there is no way to determine if a text file is an
AsciiDoc or not without pre-processing the file. This gives us two simple
options:
1. **Parse all text files**. We could have all files ending in `.txt` or
``README.txt`` be parsed through AsciiDoc. It will print pretty text fine
even if it isn't formatted as such. However this could be *not what the user
expects*.
2. **Pick a unique extension**. We could pick a unique extension (i.e.
`.asciidoc`) to prevent clashing. Although not directly suggested by the
author of AsciiDoc there is no standard or practice to the contrary.
Option two is recommended by myself.
Requirements
~~~~~~~~~~~~
The AsciiDoc API comes in two parts. The first is the system installation of
AsciiDoc which has a simple install_. The second part is the API script. You
can either copy this to the current directory or the application's lib folder.
There is more information on the `API page`_
The `re` package is imported here for the purpose to accomplish E-Mail address
cloaking. AsciiDoc does not offer it's own cloaking algorithm like docutils
does. So I made a simple one here to do the same. **If the expense of regex's
is too high it can be easily commented out.**
.. tip::
AsciiDoc by default runs in *safe mode* which means it will not include
external files that are **not** in the same directory as the `infile`.
However since we use a StringIO through the API it should be based on the
current working directory.

Cloak email addresses
AsciiDoc API does not have a `cloak_email_addresses` option. We can do the
same with a set of regex but that can be expensive. Keep section commented
to disable. So ``a...@mail.example.com`` becomes:
-----------
<a class="reference"
href="mailto:abc%40mail.example.org";>
abc<span>@</span>mail<span>.</span>example<span>.</span>org</a>
-----------

email2 = email2.replace(".", "<span>.</span>")
