1.6 * improved proof by cases and induction:
1.7 + - divinate induct rule instantiation (excessive ?P bindings no longer required);
1.8 + - proper enumeration of all possibilities of set/type rules (as a consequence
1.9 + facts may be also passed through *type* rules without further ado);
1.10 + - added 'print_induct_rules' (covered by help item in Proof General > 3.3);
1.11 - moved induct/cases attributes to Pure;
1.12 - - added 'print_induct_rules' (covered by help item in Proof General > 3.3);
1.13 - generic setup instantiated for FOL and HOL;
1.14 - - removed obsolete "(simplified)" and "(stripped)" options;
1.15 + - removed obsolete "(simplified)" and "(stripped)" options of methods;
