  // = DESCRIPTION
  //     As there is no such thing as text-based programs on Windows
  //     CE.  We need to create a windows to read the command prompt
  //     and bridge the output windows with the original ACE program
  //     entry point.  You'll need to link your program with
  //     "ace-windows.lib" for this to work.  You can refer to
  //     $ACE_ROOT/WindowsCE/Main for how I use a dialog box to run
  //     the original ACE programs.  This is certainly not the only
  //     way to use ACE in Windows programs.
