tuned signature;

moved global state to structure Document (again);

moved Outer_Syntax.load_thy to Thy_Load.load_thy; tuned signatures; tuned module dependencies;

less stateful outer_syntax;

discontinued odd Position.column -- left-over from attempts at PGIP implementation; Position.offset discriminates postions precisely, now also available for Position.line/line_file;

discontinued special treatment of hard tabulators;

eliminated hard tabs;

added translation to fix critical pair between abbreviations for surj and ~=

floor and ceiling definitions are not code equations -- this enables trivial evaluation of floor and ceiling

standardized String.concat towards implode;

more abstract Thy_Load.load_file/use_file for external theory resources; prefer Boogie_Loader.parse_b2i on already loaded text, bypassing former File.fold_lines optimization;

comment;

clarified Thy_Load.digest_file -- read ML files only once;

tuned signature;

simplified make_option/dest_option; added make_variant/dest_variant -- usual representation of datatypes;

explicit Document.Node.Header, with master_dir and thy_name; imitate ML path operations more closely;

explicit indication of type Symbol.Symbol;

simplified Symbol based on lazy Symbol.Interpretation -- reduced odd "functorial style"; tuned implicit build/init messages;

make SML/NJ happy + tuning

moved ATP dependencies to HOL-Plain, where they belong

better setup for experimental "z3_atp"

64bit versions of some mira configurations

removed unused mira configuration

tuning options to avoid spurious isabelle test failures

clarified record syntax: fieldext excludes the "more" pseudo-field (unlike 2f885b7e5ba7), so that errors like (| x = a, more = b |) are reported less confusingly;
