2012-03-19 wenzelm 2012-03-19 allow keyword tags to be redefined, but not the command category;

2011-09-02 wenzelm 2011-09-02 tuned;

2010-08-15 wenzelm 2010-08-15 rename "unit" to "atom", to avoid confusion with the unit type;
2010-08-09 wenzelm 2010-08-09 Isabelle_Process: separate input fifo for commands (still using the old tty protocol); some partial workarounds for Cygwin;

2010-07-27 wenzelm 2010-07-27 simplified/clarified theory loader: more explicit task management, kill old versions at start, commit results only in the very end, non-optional master dependency, do not store text in deps; explicit Thy_Info.toplevel_begin_theory, which does not maintain theory loader database; Outer_Syntax.load_thy: modify Toplevel.init for theory loading, and avoid slightly odd implicit batch mode of 'theory' command; added Thy_Load.begin_theory for clarity; structure ProofGeneral.ThyLoad.add_path appears to be old ThyLoad.add_path to Proof General, but actually operates on new Thy_Load.master_path instead -- for more precise imitation of theory loader; moved some basic commands from isar_cmd.ML to isar_syn.ML; misc tuning and simplification;
2010-07-25 wenzelm 2010-07-25 simplified handling of theory begin/end wrt. toplevel and theory loader;
