2016-02-17 wenzelm 2016-02-17 merged
2016-02-17 wenzelm 2016-02-17 clarified file names;
2015-08-17 wenzelm 2015-08-17 explicit debug flag for ML compiler;

2014-03-27 wenzelm 2014-03-27 redirect ML_Compiler reports more directly: only the (big) parse tree report is deferred via Execution.print (NB: this does not work for asynchronous "diag" commands); more explicit ML_Compiler.flags;
2014-03-27 wenzelm 2014-03-27 clarified Isabelle/ML bootstrap, such that Execution does not require ML_Compiler;
2014-03-25 wenzelm 2014-03-25 proper configuration option "ML_print_depth"; proper ML_exception_trace for HOL-TPTP;
2014-03-25 wenzelm 2014-03-25 added command 'SML_file' for Standard ML without Isabelle/ML add-ons;

2013-04-08 wenzelm 2013-04-08 prefer pretty_exn where possible -- NB: low-level General.exnMessage may still be used elsewhere (e.g. by the ML compiler itself);
