kuncar [Fri, 18 May 2012 15:08:08 +0200] rev 47941
don't generate code in Word because it breaks the current code setup
blanchet [Thu, 17 May 2012 13:36:23 +0200] rev 47940
robustly parse Z3 4.0's output (with outcome appearing on first rather than last line)
blanchet [Thu, 17 May 2012 13:36:23 +0200] rev 47939
added "Collect_cong" to cover extensionality of "Collect" (special cases of "ext" pass through the relevant filter)
kuncar [Wed, 16 May 2012 19:20:19 +0200] rev 47938
remove the generation of a code certificate from the Quotient package (mainly from quotient_def), because it's in lift_definition now
kuncar [Wed, 16 May 2012 19:17:20 +0200] rev 47937
generate abs_eq, use it as a code equation for total quotients; no_abs_code renamed to no_code; added no_code for quotient_type command
kuncar [Wed, 16 May 2012 19:15:45 +0200] rev 47936
infrastructure that makes possible to prove that a relation is reflexive
blanchet [Wed, 16 May 2012 18:16:51 +0200] rev 47935
temporarily disable "ext" rule helpers until Metis supports them (and until they are properly evaluated)
blanchet [Wed, 16 May 2012 18:16:51 +0200] rev 47934
lower skolem penalty to ensure that some useful facts with existentials, e.g. congruence of "setsum", eventually get picked up
blanchet [Wed, 16 May 2012 18:16:51 +0200] rev 47933
treat sets specially in relevance filter, as they used to, to avoid cluttering the problem with facts about Set.member and Collect
blanchet [Wed, 16 May 2012 18:16:51 +0200] rev 47932
get ready for automatic generation of extensionality helpers
