upgrade "isabelle build" to Isabelle/Scala;

prefer plain "isabelle" from PATH within Isabelle settings environment;

isabelle_process is superseded by "isabelle process" tool; tuned tool usage; misc updates and tuning of "system" manual;

clarified messages, notably on Windows where CPU time of poly.exe is not measured;

clarified modules;

clarified files;

clarified files;

don't throw an exception when trying to print an error message

eta-expansion done right in "primcorec"

clarified: constructors in the sense of the code generator are not invertible; correct treatment of constructors with same name but different type; moved doubtful comment to corresponding function call

moved

merged

obsolete;

clarified interactive mode, which is relevant for ML prompts;

more careful print_depth on startup;

ignore SIGINT in waiting wrapper process; proper "bash_process.c" and "build" within component;

more robust cleanup; more defensive timing value;

isabelle.Build uses ML_Process directly; isabelle_process is for batch mode only; removed unused feeder (already part of "isabelle console");

tuned;

print timing like lib/scripts/timestop.bash;

prefer explicit locale;

bash process with builtin timing;

elapsed time in milliseconds (cf. Time.now in Poly/ML);

support for timing of the managed process;

tuned;

proper support for RAW_ML_SYSTEM;

tuned signature;

separate Isabelle_Process.init_options after Options.load_defaults, notably for "isabelle console";

back to external line editor, due to problems of JLine with multithreading of in vs. out;

ignore execeptions that usually occur due to shutdown;

clarified initial ML;

isabelle console is based on Isabelle/Scala;

clarified process interrupt: exactly one signal (like thread interrupt);

tuned signature;

more abstract Session.start, without prover command-line; Isabelle_Process.apply is directly based on ML_Process; clarified Isabelle_Process.main command-line; tuned signature;

removed pointless option: this is meant for web services using Isabelle/Scala, not command-line tools;

prospective command line entry point for simplified isabelle_process;

tuned signature;

proper Path.print for user messages;

discontinued cd, pwd;

tuned -- more standard operations;

File.bash_string operations in ML as in Scala -- exclusively for GNU bash, not perl and not user output; clarified treatment of whitespace in some bash scripts;

clarified treatment of DEL; tuned signature;

clarified RAW_ML_SYSTEM;

tuned;

Bash.process always uses a closed script instead of an open argument list, for extra robustness on Windows, where quoting is not well-defined; more robust File.bash_escape; more robust treatment of ML_OPTIONS; clarified prover args (again);

manage the underlying ML process in Scala;

clarified modules;

tuned signature;
