Open-Source Software

Software development tools are sometimes expensive. To reduce development cost, the sourcecode parts which are not a corporate secret can be developed as an open-source project. Lots of otherwise expensive development tools are free in that case.

The following API's can be used for free in Open-source projects:
API Windows Unix/Linux/BSD Apple OSX
Trolltech QT 2 X X
Trolltech QT 3 X X
