+.SH "BEST PRACTICE"
+.IX Header "BEST PRACTICE"
+\&\fBFatal has been obsoleted by the new autodie pragma.\fR Please use
+autodie in preference to \f(CW\*(C`Fatal\*(C'\fR.  autodie supports lexical scoping,
+throws real exception objects, and provides much nicer error messages.
+.PP
+The use of \f(CW\*(C`:void\*(C'\fR with Fatal is discouraged.
+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\f(CW\*(C`Fatal\*(C'\fR provides a way to conveniently replace
+functions which normally return a false value when they fail with
+equivalents which raise exceptions if they are not successful.  This
+lets you use these functions without having to test their return
+values explicitly on each call.  Exceptions can be caught using
+\&\f(CW\*(C`eval{}\*(C'\fR.  See perlfunc and perlvar for details.
+.PP
+The do-or-die equivalents are set up simply by calling Fatal's
+\&\f(CW\*(C`import\*(C'\fR routine, passing it the names of the functions to be
+replaced.  You may wrap both user-defined functions and overridable
+CORE operators (except \f(CW\*(C`exec\*(C'\fR, \f(CW\*(C`system\*(C'\fR, \f(CW\*(C`print\*(C'\fR, or any other
+built-in that cannot be expressed via prototypes) in this way.
+.PP
+If the symbol \f(CW\*(C`:void\*(C'\fR appears in the import list, then functions
+named later in that import list raise an exception only when
+these are called in void context\-\-that is, when their return
+values are ignored.  For example
+.PP
+.Vb 1
+\&    use Fatal qw/:void open close/;
+\&
+\&    # properly checked, so no exception raised on error
+\&    if (not open(my $fh, \*(Aq<\*(Aq, \*(Aq/bogotic\*(Aq) {
+\&        warn "Can\*(Aqt open /bogotic: $!";
+\&    }
+\&
+\&    # not checked, so error raises an exception
+\&    close FH;
+.Ve
+.PP
+The use of \f(CW\*(C`:void\*(C'\fR is discouraged, as it can result in exceptions
+not being thrown if you \fIaccidentally\fR call a method without
+void context.  Use autodie instead if you need to be able to
+disable autodying/Fatal behaviour for a small block of code.
+.SH DIAGNOSTICS
+.IX Header "DIAGNOSTICS"
+.ie n .IP "Bad subroutine name for Fatal: %s" 4
+.el .IP "Bad subroutine name for Fatal: \f(CW%s\fR" 4
+.IX Item "Bad subroutine name for Fatal: %s"
+You've called \f(CW\*(C`Fatal\*(C'\fR with an argument that doesn't look like
+a subroutine name, nor a switch that this version of Fatal
+understands.
+.ie n .IP "%s is not a Perl subroutine" 4
+.el .IP "\f(CW%s\fR is not a Perl subroutine" 4
+.IX Item "%s is not a Perl subroutine"
+You've asked \f(CW\*(C`Fatal\*(C'\fR to try and replace a subroutine which does not
+exist, or has not yet been defined.
+.ie n .IP "%s is neither a builtin, nor a Perl subroutine" 4
+.el .IP "\f(CW%s\fR is neither a builtin, nor a Perl subroutine" 4
+.IX Item "%s is neither a builtin, nor a Perl subroutine"
+You've asked \f(CW\*(C`Fatal\*(C'\fR to replace a subroutine, but it's not a Perl
+built-in, and \f(CW\*(C`Fatal\*(C'\fR couldn't find it as a regular subroutine.
+It either doesn't exist or has not yet been defined.
+.ie n .IP "Cannot make the non-overridable %s fatal" 4
+.el .IP "Cannot make the non-overridable \f(CW%s\fR fatal" 4
+.IX Item "Cannot make the non-overridable %s fatal"
+You've tried to use \f(CW\*(C`Fatal\*(C'\fR on a Perl built-in that can't be
+overridden, such as \f(CW\*(C`print\*(C'\fR or \f(CW\*(C`system\*(C'\fR, which means that
+\&\f(CW\*(C`Fatal\*(C'\fR can't help you, although some other modules might.
+See the "SEE ALSO" section of this documentation.
+.ie n .IP "Internal error: %s" 4
+.el .IP "Internal error: \f(CW%s\fR" 4
+.IX Item "Internal error: %s"
+You've found a bug in \f(CW\*(C`Fatal\*(C'\fR.  Please report it using
+the \f(CW\*(C`perlbug\*(C'\fR command.
+.SH BUGS
+.IX Header "BUGS"
+\&\f(CW\*(C`Fatal\*(C'\fR clobbers the context in which a function is called and always
+makes it a scalar context, except when the \f(CW\*(C`:void\*(C'\fR tag is used.
+This problem does not exist in autodie.
+.PP
+"Used only once" warnings can be generated when \f(CW\*(C`autodie\*(C'\fR or \f(CW\*(C`Fatal\*(C'\fR
+is used with package filehandles (eg, \f(CW\*(C`FILE\*(C'\fR).  It's strongly recommended
+you use scalar filehandles instead.
