It's licensed under Gnu GPL if anyone want to know.. (read COPYING)

Requirements:

QT 3 (3.0.3 is prolly recommended)
And ANSI/ISO compliant c++ compiler with libraries.
(I've done all the development using gcc 3.0.x, with some patches from mandrake)

gcc 2.96's STL (from Mandrake 8.2) was not compliant enough to compile it.
