Automatic C/C++ HTML documentation generator

I've been researching automatic HTML documentation generators and have come
accross a couple of options so far:

- Cocoon http://www.stratasys.com/software/cocoon/
- DOC++ http://www.zib.de/Visual/software/doc++/index.html

The source is available for both, but I'm not entirely sure yet that DOC++
can be compiled with VC++ to run on WinNT, which is what I need to use.

Does anybody have experience with both or either of these and can share an
opinion, or do you know of any others that are worth researching before I
dive in?

There didn't appear to be pre-built versions for NT. If I end up making
one, I can make it available to you. Let me know if you're interested.

I've used Cocoon a little. It's not bad, bufor me it took a litle confguring to get the output to look the way I want. Once, you've got yourconfiguration file set up, it's easy as pie to use!

The downside though, is that if you've got a lot of old code that you want to "Cocoon" you have have to spend some time decorating it in a way that cocoon can parse.
