2006-09-13 paulson 2006-09-13 Tweaks to is_fol_term, the first-order test. We don't count "=" as a connective since this test is applied to clause forms.
2006-08-25 paulson 2006-08-25 better skolemization, using first-order resolution rather than hoping for the right result
2006-08-08 paulson 2006-08-08 more explict variable names

2005-11-18 mengj 2005-11-18 -- removed "check_is_fol" from "make_nnf" so that the NNF procedure doesn't check whether a thm is FOL. -- added "check_is_fol_term", which is the same as "check_is_fol", but takes a "term" as input. -- added "check_is_fol" and "check_is_fol_term" into the signature.
2005-11-16 paulson 2005-11-16 new version of "tryres" allowing multiple unifiers (apparently needed for Skolemization of higher-order theorems)
2005-11-09 paulson 2005-11-09 Skolemization by inference, but not quite finished
2005-10-28 wenzelm 2005-10-28 renamed Goal constant to prop;
