this is what I used to modify the Cubebot source code...
I'm posting it for people who prefer to use an IDE instead of Emacs, Vim, etc. like me
you may download KDevelop at: http://www.kde.org
, however it's actually included with most of the decent GNU/Linux distros. Also this project file is for KDevelop 2, not KDevelop 3 as I feel KDevelop 2 is more handy. But it should be able to open in KDevelop 3
