I don't remember that happening, but if it did, Dann can refresh my
memory.  I have never claimed a program _was_ a clone without proof.  For
Le Petite I posted the proof here in CCC.  As I did for Voyager.  As I did
for Bionic Impact.  As I did for ...

Again, this is _not_ the same thing.  Yace improved a lot, quickly.  But the
author was here participating in discussions, present on ICC, etc.  So he
didn't just "drop out of the sky".  When _that_ happens, suspicions are bound
to be tweaked...
