removed unused code

Tuned comment.

Rewrote function remove_suc, since it failed on some equations produced by recdef.

write_dimacs_sat_file now generates slightly smaller files

revised examples

code streamlining

Ressurect seq attribute accidently removed

Sort search results in order of relevance, where relevance = a) better if 0 premises for intro or 1 premise for elim/dest rules b) better if substitution size wrt to current goal is smaller Only applies to intro, dest, elim, and simp (contributed by Rafal Kolanski, NICTA)

isatool fixheaders;

with_path;

added list of theorem changes to NEWS added real_of_int_abs to RealDef.thy

added defined;

simplified union;

tuned match, unify;

tuned defs interface;

moved incr_tvar to logic.ML; added eq_var, eq_tvar, instantiate, instantiateT;

tuned norm_sort, mg_domain;

tuned instantiate interface; Logic.incr_tvar;

incr_tvar (from term.ML), incr_indexes: avoid garbage;

added has_duplicates; tuned qsort;

textual tweak

Documentation updated

reverted from fold_yield to fold_map

*** empty log message ***

tuned fold on terms and lists;

tuned assoc;

tuned fold on terms; tuned assoc;

tuned min_key, max_key;

replaced foldl_XXX by canonical fold_XXX; canonical arguments for add_term_varnames, add_tvarsT, add_tvars, add_vars, add_frees,

tuned;

tuned fold on terms;

* Pure/library.ML: several combinators for linear functional transformations; * Pure/library.ML: canonical list combinators fold, fold_rev, and fold_yield; * Pure/term.ML: combinators fold_atyps, fold_aterms, fold_term_types, fold_types;

optimize no_types_needed, remove exception handler

tuned;

lucas - slightly cleaned up. Removed redudent copy of Symtab structure.

* Improved 'oracle' command -- type-safe;

no open Logic;

removed itlist, rev_itlist -- use fold_rev, fold instead; improved end_itlist;

replaced itlist by fold_rev; replaced rev_itlist by fold;

replaced itlist by fold_rev;

use sys_error instead of exception Internal; actually use Termtab; tuned;

sys_error;

type-safe 'oracle' command;

added dest_table;

invoke_oracle: do not keep theory value, but theory_ref;
