PerlQt is Copyright (C) 1997-2000, Ashley Winters PerlQt is mostly distributed under the LGPL, and is not distributed under the QPL license. Since this is a Qt-1.x application as defined by the Qt Free Software License, the obligitory notification: PerlQt requires the Qt library, which is copyright Troll Tech AS. Freely distributable programs may generally use Qt for free, see README.QT for details The notable exceptions to the LGPL licensing include the two Perl modules, Pig.pm and SigSlot.pm. Those are distributed under the Artistic/GPL licensing scheme as layed out by Perl. Everything in the Qt*/ directories is probably public domain, since I don't make any claims to it.
