OpenRules licensing policy is
dual that makes OpenRules software available to both
open source and commercial customers.
GPL Licenses for Open Source Projects. OpenRules is
available to everyone under the terms of the most popular Open
Source license known as "GNU General Public License" (GPLv2).
GPL requires any "derivative
works" to be also covered by GPL. In particular, it
means that source code of these works be made publicly available. If you are developing and/or
using open source applications under the terms of GPL
or a compatible Open Source License,
then you are free to use OpenRules without any license fee.
