I have a set of LaTeX templates for IDLdoc. I'm still polishing them up a bit, but they will be in IDLdoc 3.2; printed documentation in the form of LaTeX and DocBook output will be the major features.

Here's an example PDF generated by the IDLdoc trunk. Compare to the DocBook output (PDF) [previously mentioned](http://michaelgalloy.com/2008/06/26/docbook-output-from-idldoc.html).
