but you should be able to get the idea. If people bitch about the links
that don't work I'll see if I can fix them.
The skinning is in the Html file.
Here's an example:
http://www.mcvoy.com/lm/bkdocs/UG/
is the source, you can look at those files, they are nroff -ms source,
and then look at
http://www.mcvoy.com/lm/bkdocs/UG/tmp
and you'll see the web version of the docs. Which is pretty useful.
You've got all the .NH 1 headers in the table of contents down the
left side, and when you click one of them it shows you the .NH 2,
.NH 3 etc headers for just that section.
And if you go to
http://www.mcvoy.com/lm/bkdocs/UG/tmp/map.html
you can get html versions of any .NH 1 section, or the entire thing as one
page.
It's a ~1700 line perl program (perl 4ish) and it has some ability to skin
the content. Source in
