=head1 NAME

Test::Trap::Builder::PerlIO - Capture strategy using PerlIO::scalar

=head1 VERSION

Version 0.3.5

=head1 DESCRIPTION

This module provides a capture strategy I<perlio>, based on
PerlIO::scalar, for the trap's output layers.  Note that you may
specify different strategies for each output layer on the trap.

See also L<Test::Trap> (:stdout and :stderr) and
L<Test::Trap::Builder> (output_layer).

=head1 CAVEATS

These layers use in-memory files, and so will not (indeed cannot) trap
output from forked-off processes -- including system() calls.

Threads?  No idea.  It might even work correctly.

=head1 BUGS

Please report any bugs or feature requests directly to the author.
