nipkow [Wed, 23 Jul 1997 17:44:15 +0200] rev 3569
Simplified a few proofs because of improved simplification.
nipkow [Wed, 23 Jul 1997 17:43:42 +0200] rev 3568
Prod.ML: Added split_paired_EX and lots of comments about failed attempts to
automate reasoning about products.
simpdata.ML: added simplification procedure for simplifying existential
statements of the form ? x. ... & x = t & ...

paulson [Wed, 23 Jul 1997 11:54:32 +0200] rev 3565
Now rename_params_rule merely issues warnings--and does nothing--if the
renaming cannot be performed. Previously it raised a fatal error.
paulson [Wed, 23 Jul 1997 11:52:22 +0200] rev 3564
Now Datatype.occs_in_prems prints the necessary warning ITSELF.
It is also easier to invoke and even works if the induction variable
is a parameter (rather than a free variable).
paulson [Wed, 23 Jul 1997 11:50:26 +0200] rev 3563
Uses new version of Datatype.occs_in_prems

Cosmetic changes: margins, indentation, ...
paulson [Tue, 22 Jul 1997 11:49:44 +0200] rev 3544
Now possibility_tac is an explicit function, in order to delay
the evaluation of \!simpset
