The CLIPS FAQ question #4 gives the licence:
It looks like a very free licence: they grant "rights to use, copy,
modify, merge, publish, distribute, and/or sell copies of the Software,
and to permit persons to whom the Software is furnished to do so."
Since they used "and/or", it seems that you can both modify it and
redistribute the modifications, which would make it free software.
(Note that if something is under "no licence" -- ie you can't find a
licence -- you need to assume that it's all rights reserved and that it
can be neither modified nor redistributed. That's the default.)
