Non-Local Exits
***************

   Sometimes when your program detects an unusual situation inside a
deeply nested set of function calls, you would like to be able to
immediately return to an outer level of control.  This section
describes how you can do such "non-local exits" using the `setjmp' and
`longjmp' functions.
