debug
     :: Forces to enter into debugging mode.

     Function `debug' is a function with no argument.  It can be called
     without `()'.

   * In the debug-mode, you are prompted by `(debug)' and the debugger
     is ready for commands.  Typing in `quit' (Note! without a
     semicolon.) brings you to exit the debug-mode.

   * See *Note Debugger:: for details.
