Is it GUI? Or is it IDE?

[Daniel J Sebald]

  --force-gui             Force graphical user interface to start.
  --no-gui                Disable the graphical user interface.

Before getting too far along, it might worth re-opening the discussion 
of the phrase "gui" (graphical user interface) versus "ide" (integrated 
development environment) because this was a point of contention in the 
past.  I may be wrong, but from those threads about four months ago my 
conclusion was that things seemed to be leaning toward "ide".

On related syntax issues:

1) Might there be a better option name that doesn't use the word 
"force".  When I think of software applications, "force" is something 
that sort of comes with "caveat emptor" connotations, i.e., something 
that typically shouldn't be done, but give it a try and maybe you'll be 
lucky.  "with-gui" where "with" is sort of the opposite of "no", 
perhaps.  "--gui" would be fine too.

2) I see "verbose_usage" isn't set up to conditionally display options 
based upon wether GUI/IDE is compiled with Octave.  I'm fine with that, 
but some new users might be confused by... unless (and this may be 
preferred) somewhere around here:

  if (force_gui_option && no_gui_option)
    {
      error ("error: only one of --force-gui and --no-gui may be used");
      usage ();
    }

there is something like

  if (force_gui_option)
    if (no_gui_option)
      {
        error ("error: only one of --force-gui and --no-gui may be used");
        usage ();
      }
#if NO_GUIIDE_COMPILE_IN_THIS_THING
    else
      {
        error ("error: GUI/IDE was not compiled with application");
        usage ();
      }
#endif
