I'm working on the final typesetting for the mod_perl 2 User's Guide. My brain is filled with style conventions, and index items, and installation options, Oh My! In the process, I've nearly tripled the size of chromatic's Pod::PseudoPod::LaTeX (a subclass of my Pod::PseudoPod), carrying it from the styles needed for a novel (text and headings), to the styles needed for a full-powered technical book.
I have to say, I'm really loving LaTeX. It has a package for everything. A bit like Perl, really. Also like Perl in its lovably quirky nature.
