Yes indeed - hi Chee Wee..

They use a hacked version of kdoc to generate them automatically. I keep any 
manual edits I need to make as a patch, so the next time I regenerate the 
bindings, I can just reapply that patch. The C bindings wrap about 800 
classes, 13 000 methods with 200k LOC of C/C++ generated.

I would like to tidy up the kdoc code, call it something like 'kbindgen' and 
combine the C/Objective-C/Java bindings generation into the one tool. That's 
why I didn't check that in last night, the code isn't 'secret', and it works 
- it just looks a bit of a mess.

I haven't contacted the kdoc author, Sirtaj Singh Kang to see what he thinks 
yet. Although the code could perhaps go into the ordinary kdoc as a patch - 
generating an api is just another output format for a documentation tool like 
kdoc. But my perl isn't nearly as well written as Sirtaj's stuff, and it also 
does something which kdoc wasn't intended to do - parse methods down to the 
argument level, and uses a (hard coded) symbol table.

I have C bindings for Qt 2.3.0 and KDE 2.2 already done. I didn't get them 
checked in for KDE 2.2.1 because I hit a weird dynamic linking/PIC problem 
with the Objective-C bindings, which I couldn't solve. I'll send them to you, 
along with the current kdoc C++ -> C source converter.
