I have seen the frames version. As for what I had in mind, not really...
I want something on the page with the top-level sections (not
necessarily the entire tree) that I can then put to the side. Rather
like a conventional site navigation sidebar. (I also want to customize
more of the page, but that's a different issue.)

I'm afraid the "obvious" directory isn't obvious to me... do people
usually put their source files and makefiles online with their

I'd noticed that... the last bit of output is always "doing section
links..." as it does the navigation.

I have no problem with doing this in perl instead of LaTeX - in fact
that's what I assumed I would have to do, from within the
top_navigation_panel subroutine. What I'm having trouble with is
figuring out where I can find 1) a variable with all of the section
titles, numbers, and filenames that I can parse to build my menu, and 2)
some indicator of what section is currently being processed. latex2html
obviously knows what section it's working on when it runs
top_navigation_panel and builds the next and previous links, because it
does them correctly.
The %section_info hash seems to have the information I'm looking for in
point 1, but I'm still trying to figure out what the structure of that

That's the problem with world domination. Nobody is willing to wait for
