KDevelop4

Not sure about a new release. David Nolden has been pretty busy with his
Phd recently, but despite announcing he wouldn't have time for KDeveloper
anymore, he's been committing anyway. KDevelop really is incredibly cool:
but they do need more developers working on things like spit & polish.
Which is the perfect way of getting into a really exciting and innovative
project. KDevelop already can do more with your C++ codebase than any IDE
I've used (and those include eclipse, visual studio, netbeans, qt-creator,
borland vc++ and Emacs).
