- * @author Jeremy Cowgar <jeremy@cowgar.com>
- *
- * @package Text_Wiki
- *
- * @todo [http://google.com] becomes 1 with a LaTeX footnote in subscript.
- * This should be a normal LaTeX footnote associated with the
- * previous word?
- *
- * @todo parse "..." to be ``...''
- *
- * @todo parse '...' to be `...'
- *
- * @todo move escape_latex to a static function, move escaping to the
- * individual .php files they are associated with
- *
- * @todo allow the user to add conf items to do things like
- * + A custom document header
- * + Custom page headings
- * + Include packages
- * + Set Title, Author, Date
- * + Include a title page
- * + Not output Document Head/Foot (maybe combinding many pages?)
