2006-11-17 wenzelm 2006-11-17 more robust syntax for definition/abbreviation/notation;
2006-11-10 wenzelm 2006-11-10 tuned;
2006-11-07 wenzelm 2006-11-07 tuned specifications;
2006-10-09 wenzelm 2006-10-09 attribute symmetric: zero_var_indexes;

2005-12-08 wenzelm 2005-12-08 tuned sources and proofs
2005-07-12 avigad 2005-07-12 added lemmas to OrderedGroup.thy (reasoning about signs, absolute value, triangle inequalities) added lemmas to Ring_and_Field.thy (reasoning about signs, fractions, etc.) renamed simplification rules for abs (abs_of_pos, etc.) renamed rules for multiplication and signs (mult_pos_pos, etc.) moved lemmas involving fractions from NatSimprocs.thy added setsum_mono3 to FiniteSet.thy added simplification rules for powers to Parity.thy
