-   This plugin adds the <tex>...</tex> tags which allow you to
-   integrate formulas into wiki pages, if you have the MimeTeX
-   package (from John Forkosh) installed. You can get it from
-   [http://www.forkosh.com/mimetex.html] (source or as binary)
-   
-   The original idea and implementation of this plugin was done by
-   Francois Vanderseypen <illumineo*users·sf·net> as you can see at
-   [http://netron.sourceforge.net/ewiki/netron.php?id=MimeTeX]
-   
-   <tex> \aleph = \bigsum_{\alpha,\beta}\Bigint_{0}^{\infty}\:\Gamma_{\alpha\beta}(x)\,dx </tex>
