-# See LICENSE for details.

-"""Rudimentary slide support for Lore.

-TODO:

- - Complete mgp output target

- - syntax highlighting

- - saner font handling

- - probably lots more

- - Add HTML output targets

- - one slides per page (with navigation links)

- - all in one page

-Example input file::

- <html>

- <head><title>Title of talk</title></head>

- <body>

- <h1>Title of talk</h1>

- <h2>First Slide</h2>

- <ul>

- <li>Bullet point</li>

- <li>Look ma, I'm <strong>bold</strong>!</li>

- <li>... etc ...</li>

- </ul>

- <h2>Second Slide</h2>

- <pre class="python">

- # Sample code sample.

- print "Hello, World!"

- </pre>

- </body>

- </html>
