has released Kylix 'Open Edition' for download from its site.
From the FAQ:
What is Kylix Open Edition?
Kylix Open Edition is the version of Kylix specifically designed
for open-source development and for building applications that are
distributed under the GPL.
What is the GPL and how does it affect the distribution
of applications that I create with Kylix Open Edition?
The GPL, GNU General Public License, is a free software
(http://www.gnu.org/philosophy/free-sw.html) distribution license,
often referred to as an open-source license. GPL , defined by
Richard Stallman of the Free Software Foundation, was created to
provide a protected means of distributing free software and to
ensure that derivative works also remain free. A copy of the GPL
license can be found at http://www.gnu.org/copyleft/gpl.html.
The Kylix Open Edition ships with CLX libraries under the GPL
license. As such, any applications that are built with a CLX
library must make their sources freely available and distribute
them under the terms of the GPL license as well. For example, any
application built with the Kylix Open Edition must link to the
BaseCLX? library and will therefore be bound to the GPL.
Furthermore, the Open Edition IDE End User License Agreement (EULA)
also requires that any software developed with Kylix Open Edition
must be released to the general public under the terms of the GPL.
Any other use of Kylix Open Edition IDE would be in legal violation
of the license agreement.
