Sun, 01 May 2011 22:36:58 +0200 blanchet use "metis", not "metisFT", to reconstruct proofs found in fully-typed mode -- "metisFT" is just too slow...
Sun, 01 May 2011 21:53:32 +0200 blanchet beware of polymorphic types in typed translation symbol declarations -- match alpha-equivalent types and, more importantly, prevent unsoundnesses by generating type constraints on the arguments of a polymorphic symbols (otherwise "hAPP" can be given any result type)
Sun, 01 May 2011 18:57:45 +0200 blanchet minor doc fixes
Sun, 01 May 2011 18:52:38 +0200 blanchet adapt to new type system names
Sun, 01 May 2011 18:37:25 +0200 blanchet restructured type systems some more -- the old naming schemes had "argshg diff |less" and "tagshg diff |less" as equivalent and didn't support a monomorphic version of "tags"
Sun, 01 May 2011 18:37:25 +0200 blanchet take "partial_types" option with a grain of salt
Sun, 01 May 2011 18:37:25 +0200 blanchet fixed SPASS fact offset calculation and report unexpected unsound proofs with so-called sound encodings

Sun, 01 May 2011 18:37:25 +0200 blanchet recognize more SystemOnTPTP errors
Sun, 01 May 2011 18:37:25 +0200 blanchet cleanup proxification/unproxification and make sure that "num_atp_type_args" is called on the proxy in the reconstruction code, since "c_fequal" has one type arg but the unproxified equal has 0
Sun, 01 May 2011 18:37:25 +0200 blanchet make sure that fequal keeps its type arguments for mangled type systems
Sun, 01 May 2011 18:37:24 +0200 blanchet no needless "fequal" proxies if "explicit_apply" is set + always have readable names
Sun, 01 May 2011 18:37:24 +0200 blanchet shorten readable names -- they can get really long with monomorphization, which actually slows down the ATPs
Sun, 01 May 2011 18:37:24 +0200 blanchet avoid Type.TYPE_MATCH exception for "True_or_False" for "If"
Sun, 01 May 2011 18:37:24 +0200 blanchet proper handling of partially applied proxy symbols
