Math output

Adam,
I've implemented [math-output available in ReST since Docutils 0.8](http://docutils.sourceforge.net/docs/ref/rst/directives.html#math). Note also that when testing I encountered [this issue](http://sourceforge.net/p/docutils/bugs/228/) and therefore I updated my distro-provided docutils with [this patch](http://sourceforge.net/p/docutils/code/7646).
On the HTML side, it uses www.mathjax.org
On the PDF side, give it a try and look at [this question](http://www.princexml.com/forum/topic/1887/future-of-math-typesetting-in-prince)
