+* 
+* @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?)
