=head1 NAME
Tie::StdHandle - base class definitions for tied handles
=head1 SYNOPSIS
package NewHandle;
require Tie::Handle;
@ISA = qw(Tie::Handle);
sub READ { ... } # Provide a needed method
sub TIEHANDLE { ... } # Overrides inherited method
package main;
tie *FH, 'NewHandle';
=head1 DESCRIPTION
The B<Tie::StdHandle> package provide most methods for file handles described
in L<perltie> (the exceptions are C<UNTIE> and C<DESTROY>). It causes tied
file handles to behave exactly like standard file handles and allow for
selective overwriting of methods.
