Jim Bublitz has been industriously working on getting the Python bindings for KDE 4 into shape. Part of that work is documentation of course and for that Jim has put together a very handy documentation viewer which combines reference docs with code samples and example code all in one easy to navigate package. One of the classic documentation problems for GUIs which are as customisable as Qt/KDE, is that everyone can, and often does, have their own visual style configured for their desktop. This of course means that any screenshots accompanying documentation simply don't match what is in front of the user most of the time. Having real widgets displayed and operational in the reference docs themselves solves this problem for Python developers at least. I think it's real neat.

reuse Qt Assistant
maybe check CMake2assistant:
http://qt-apps.org/content/show.php/CMake2assistant
"This tool parses CMake output to generate an HTML cross-referenced version of CMake commands and modules. It also generates a .dcf file which can be used to integrate the CMake documentation in Qt Assistant v3 or v4."
It could be nice to reuse Qt Assistant and just generate dcf file.
