Latex Everything can produce PDF documents of everything on your site with 
Latex. Or at least everything worth putting into a PDF.
Latex Everything can make PDF documents from individual posts and groups of 
posts like categories, tags and custom taxonomy terms. The plugins contains 
everything a theme needs to define its own Latex templates, and link to the PDFs 
produced.

Ever noticed that when you try to upload a <code>.tex</code> file to your WordPress blog, it’s mysteriously blocked? This plugin simply allows for LaTeX file uploading.
In particular, it supports the <code>.tex</code>, <code>.latex</code>, <code>.ps</code>, and <code>.dvi</code> extensions. <code>.pdf</code> is already supported by the WordPress core.
This plugin is a component of the <a href="http://ecs.mit.edu" rel="nofollow ugc">MIT Educational Collaboration Space</a> project at the <a href="http://math.mit.edu/" rel="nofollow ugc">MIT Department of Mathematics</a>.
