2009-02-21 nipkow 2009-02-21 removed redundant thms
2009-01-26 haftmann 2009-01-26 stripped Id
2008-12-03 huffman 2008-12-03 fixed proofs due to changes in Int.thy
2008-10-10 haftmann 2008-10-10 `code func` now just `code`
2008-05-07 berghofe 2008-05-07 Deleted subset_antisym in a few proofs, because it is accidentally applied to predicates as well.
2008-04-04 haftmann 2008-04-04 more new primrec
2008-04-02 haftmann 2008-04-02 tuned towards code generation
2008-03-17 kleing 2008-03-17 fixed broken bintrunc lemma
2008-02-17 huffman 2008-02-17 New simpler representation of numerals, using Bit0 and Bit1 instead of BIT, B0, and B1
2008-01-15 haftmann 2008-01-15 joined theories IntDef, Numeral, IntArith to theory Int
2007-11-08 wenzelm 2007-11-08 eliminated illegal schematic variables in where/of; tuned;
2007-10-21 nipkow 2007-10-21 Eliminated most of the neq0_conv occurrences. As a result, many theorems had to be rephrased with ~= 0 instead of > 0.

2007-08-20 kleing 2007-08-20 * HOL-Word: New extensive library and type for generic, fixed size machine words, with arithemtic, bit-wise, shifting and rotating operations, reflection into int, nat, and bool lists, automation for linear arithmetic (by automatic reflection into nat or int), including lemmas on overflow and monotonicity. Instantiated to all appropriate arithmetic type classes, supporting automatic simplification of numerals on all operations. Jointly developed by NICTA, Galois, and PSU. * still to do: README.html/document + moving some of the generic lemmas to appropriate place in distribution
