Standalone Operation
--------------------

If you are not in Emacs at the moment but you wish to use Calc, you
must start Emacs first.  If all you want is to run Calc, you can give
the commands:

     emacs -f full-calc

or

     emacs -f full-calc-keypad

which run a full-screen Calculator (as if by `M-# b M-# c') or a
full-screen X-based Calculator (as if by `M-# b M-# k').  In
standalone operation, quitting the Calculator (by pressing `q' or
clicking on the keypad EXIT button) quits Emacs itself.
