2013-12-14 wenzelm 2013-12-14 proper context for basic Simplifier operations: rewrite_rule, rewrite_goals_rule, rewrite_goals_tac etc.; clarified tool context in some boundary cases;

2013-04-10 wenzelm 2013-04-10 more standard module name Axclass (according to file name);
2012-10-09 huffman 2012-10-09 removed support for set constant definitions in HOLCF {cpo,pcpo,domain}def commands; removed '(open)', '(set_name)' and '(open set_name)' options
2012-03-16 wenzelm 2012-03-16 outer syntax command definitions based on formal command_spec derived from theory header declarations;
2012-03-15 wenzelm 2012-03-15 prefer formally checked @{keyword} parser;
2012-03-13 wenzelm 2012-03-13 more explicit indication of def names;
2012-02-27 wenzelm 2012-02-27 prefer cut_tac, where it is clear that the special variants cut_rules_tac or cut_facts_tac are not required;
2011-11-27 wenzelm 2011-11-27 more antiquotations;
2011-10-28 wenzelm 2011-10-28 tuned Named_Thms: proper binding;
2011-08-08 huffman 2011-08-08 HOLCF: fix warnings about unreferenced identifiers
2011-08-08 huffman 2011-08-08 rename Pair_fst_snd_eq to prod_eq_iff (keeping old name too)
2011-04-17 wenzelm 2011-04-17 added Binding.print convenience, which includes quote already;
2011-04-17 wenzelm 2011-04-17 report Name_Space.declare/define, relatively to context; added "global" variants of context-dependent declarations;
2011-04-16 wenzelm 2011-04-16 modernized structure Proof_Context;
2011-03-29 wenzelm 2011-03-29 tuned headers;
2011-01-04 huffman 2011-01-04 change some lemma names containing 'UU' to 'bottom'
2010-12-20 huffman 2010-12-20 make internal proofs for deflation and isodefl theorems more robust, by avoiding calls to the simplifier for beta-reduction
2010-12-19 huffman 2010-12-19 use deflations over type 'udom u' to represent predomains; removed now-unnecessary class liftdomain;
2010-12-19 huffman 2010-12-19 type 'defl' takes a type parameter again (cf. b525988432e9)
2010-11-30 huffman 2010-11-30 internal domain package proofs use cont2cont simproc instead of a fixed list of cont rules

2010-11-27 huffman 2010-11-27 moved directory src/HOLCF to src/HOL/HOLCF; added HOLCF theories to src/HOL/IsaMakefile;
