summary

Extend the mdwn plugin to support itex using Jacques Distler's itex2MML.

notes

This is an updated form of JasonBlevins' plugin. You can see the plugin in action on my blog. The blog post lists a few additional changes you may need to make to use the plugin, including changing your page template to a MathML-friendly doctype and disabling plugins like htmlscrubber and htmltidy which would otherwise strip out the generated MathML.
