    a subclassable template class for a standalone GUI-application's startup;

    For your own stand alone programs, define a subclass of this, 

    and redefine the #main: method there.

    (of course, the other methods can also be redefined.)

    main:argv

        thats the actual program.

    suppressRCFileReading

        false here; redefine to return true, to disable the rc-file reading.

        you loose the chance of configuration, but lock the user out from any access to any smalltalk

        (if you have a user-phobia)

    allowDebugOption

        false here; redefine to return true, to enable the --debug startup option.

        if disabled, you loose the chance of debugging, but lock the user out from any access to any smalltalk

    allowScriptingOption

        false here; redefine to return true, to enable the --scripting startup option.

        if disabled, you loose the chance of remote control, but lock the user out from any access to any smalltalk
