=head1 NAME
IO::Catch - capture STDOUT and STDERR into global variables
=head1 AUTHOR
Max Maischein ( corion at cpan.org )
All code ripped from pod2test by M. Schwern
=head1 SYNOPSIS
# pre-5.8.0's warns aren't caught by a tied STDERR.
use vars qw($_STDOUT_, $_STDERR_);
tie *STDOUT, 'IO::Catch', '_STDOUT_' or die $!;
tie *STDERR, 'IO::Catch', '_STDERR_' or die $!;
# now you can access $main::_STDOUT_ and $_STDERR_
# to see the output.
