2012-08-01 wenzelm 2012-08-01 more standard bootstrapping of Pure.thy;
2012-03-18 wenzelm 2012-03-18 maintain generic context naming in structure Name_Space (NB: empty = default_naming, init = local_naming); more explicit Context.generic for Name_Space.declare/define and derivatives (NB: naming changed after Proof_Context.init_global); prefer Context.pretty in low-level operations of structure Sorts/Type (defer full Syntax.init_pretty until error output); simplified signatures;

2011-04-18 wenzelm 2011-04-18 recovered Theory.check_def: full name needs to be determined from background thy, not auxiliary ctxt (broken in 774df7c59508, caused Nitpick.all_axioms_of to produce bad results);

2010-03-22 wenzelm 2010-03-22 replaced Theory.add_axioms(_i) by more primitive Theory.add_axiom;
2010-03-20 wenzelm 2010-03-20 renamed varify/unvarify operations to varify_global/unvarify_global to emphasize that these only work in a global situation;
2010-01-04 wenzelm 2010-01-04 discontinued old TheoryDataFun, but retain Theory_Data_PP with is Pretty.pp argument to merge (still required in exotic situations -- hard to get rid of);
2010-01-04 haftmann 2010-01-04 dropped copy operation for legacy TheoryDataFun
2009-11-15 wenzelm 2009-11-15 primitive defs: clarified def (axiom name) vs. description;
