2005-12-23 ago the "skolem" attribute and better initialization of the clause database
2005-12-14 ago removed unused function repeat_RS
2005-11-28 ago Added two functions for CNF translation, used by other files.
2005-11-18 ago -- combined common CNF functions used by HOL and FOL axioms, the difference between conversion of HOL and FOL theorems only comes in when theorems are converted to ResClause.clause or ResHolClause.clause format.
2005-11-10 ago duplicate axioms in ATP linkup, and general fixes
2005-11-09 ago Skolemization by inference, but not quite finished
2005-10-28 ago got rid of obsolete prove_goalw_cterm
2005-10-28 ago Added several new functions that convert HOL Isabelle rules to FOL axiom clauses. The original functions that convert FOL rules to clauses stay with the same names; the new functions have "H" at the end of their names.
2005-10-21 ago OldGoals;
2005-10-19 ago Added files in order to use external ATPs as oracles and invoke these ATPs by calling Isabelle methods (currently "vampire" and "eprover").

2005-05-23 ago Moved some of the clausify functions from ATP/res_clasimpset.ML to res_axioms.ML.
