KDE Base API Dox. KDEBase is the SVN module with the "basic applications" needed for KDE. These include startkde (a shell script to start the whole desktop), kdesktop (the desktop), konqueror (the browser and file- manager) and lots of other things. Nearly none of it has dox.

KWin -- the window manager -- does have dox, as do some of kate's -- the text editor part -- libraries.
