#{NAME} [exitcode] - hard exit of the debugged program.  

The program being debugged is exited via exit!() which does not run
the Kernel at_exit finalizers. If a return code is given, that is the
return code passed to exit() - presumably the return code that will be
passed back to the OS. If no exit code is given, 0 is used.

If you are in interactive mode, and confirm is not set off, you are
prompted to confirm quitting. However if you do not want to be
prompted, add ! the end.  (vim/vi/ed users can use alias q!).

See also "kill" and "set confirm".'
