Yes, but LOOK at the difference between KES & CLIPS!!!  Bigger difference there
than anywhere else in the test set.  I can't understand why EVERYONE is
not using CLIPS.  With the source code available for self-modificatin (?)
it seems to me to be the best available.  (Of course I am TOTALLY unbiased).
I am, however, NOT associated with NASA or JCS in any way, just a happy
user of CLIPS.
