=head1 DESCRIPTION

B<THIS CODE IS CRAP! IT'S SO BAD IT MAKES THE I<COMPUTER> ANGRY!!!>

Do you feel that the error messages in your code don't express your
frustration with enough I<oomph>? Do screens full of stack dumps fill
you with a deep-seated rage?

Have you ever wanted to simply flip a table each time your program
dies with a cryptic, useless exception?

NOW YOU CAN.

=head1 THANKS

=head2 Limited support for Perl 5.6

Perl 5.6 predates PerlIO.  UTF-8 data may not be captured correctly.

=head1 ENVIRONMENT

=head2 PERL_CAPTURE_TINY_TIMEOUT

Capture::Tiny uses subprocesses for C<<< tee >>>.  By default, Capture::Tiny will
timeout with an error if the subprocesses are not ready to receive data within
30 seconds (or whatever is the value of C<<< $Capture::Tiny::TIMEOUT >>>).  An
alternate timeout may be specified by setting the C<<< PERL_CAPTURE_TINY_TIMEOUT >>>
environment variable.  Setting it to zero will disable timeouts.

=head1 SEE ALSO

This module was, inspired by L<IO::CaptureOutput>, which provides
similar functionality without the ability to tee output and with more
complicated code and API.  L<IO::CaptureOutput> does not handle layers
or most of the unusual cases described in the L</Limitations> section and
