2005-07-19 wenzelm 2005-07-19 Inttab.defined;
2005-07-06 wenzelm 2005-07-06 check_thy: less invocations, less verbose; tuned merge, merge_refs;

2005-06-20 wenzelm 2005-06-20 improved treatment of intermediate checkpoints: actual copy instead of extend, purge after end; tuned;
2005-06-17 wenzelm 2005-06-17 added type theory: generic theory contexts with unique identity, arbitrarily typed data, linear and graph development -- a complete rewrite of code that used to be spread over in sign.ML, theory.ML, theory_data.ML, pure_thy.ML;
2005-04-21 wenzelm 2005-04-21 superceded by Pure.thy and CPure.thy;
