NAME
       Fatal - replace functions with equivalents which succeed
       or die

SYNOPSIS
           use Fatal qw(open close);

           sub juggle { . . . }
           import Fatal 'juggle';


DESCRIPTION
       Fatal provides a way to conveniently replace functions
       which normally return a false value when they fail with
       equivalents which halt execution if they are not
       successful.  This lets you use these functions without
       having to test their return values explicitly on each
       call.   Errors are reported via die, so you can trap them
       using $SIG{__DIE__} if you wish to take some action before
       the program exits.

       The do-or-die equivalents are set up simply by calling
       Fatal's import routine, passing it the names of the
       functions to be replaced.  You may wrap both user-defined
       functions and overridable CORE operators (except exec,
       system which cannot be expressed via prototypes) in this
       way.
