added 'moreover' command;

tuned output;

tuned spacing;

ex/Antiquote.thy made new-style theory; removed ex/Antiquote.ML;

now exclusively uses rtac/dtac/etac rather than the long forms

restored the MESON examples file HOL/ex/mesontest2.ML

made a proof more robust (did not like Suc_less_eq)

Suc_less_eq now with AddIffs. How could this have been overlooked?

combined finite_Int1/2 as finite_Int. Deleted the awful "lemma" from the default claset. Used "inst"

made more robust

tidied using new "inst" rule

new meta-rule "inst", a shorthand for read_instantiate_sg

tidied

the perm_rules variable is no longer needed

tidied

replaced best_tac by force_tac, allowing some arithmetic reasoning

renamed a variable to avoid possible free/bound confusion

a possibly (?) more perspicous simprule in the "simpset" part

now based on "Main", as it should be

deleted unnecessary "simpset" part from recdef

'oops' made proper; removed 'kill_proof' (superceded by 'kill');

Added setup for primrec theory data.

get_recdef now returns None instead of raising ERROR.

Added new theory data slot for primrec equations.

Now returns theorems with correct names in derivations.

Eliminated store_clasimp.
