|
* @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?)
