kdesvn is yet another client for subversion. But it uses native
KDE API instead of a extra lib like GAMBAS and it is using the
native subversion development API instead of just parsing the
output of the command-line tool like most other clients do. It tries
to setup a look and feel like the standard filemanager of KDE and is
integrated into it via KPart.
The base C++ interface to subversion I took from the (real great) tool
Rapidsvn (see http://rapidsvn.tigris.org/) with some modifications and fixes.
