=head1 NAME
Test::Trap::Builder::TempFile - Output layer backend using File::Temp
=head1 VERSION
Version 0.2.4
=head1 DESCRIPTION
This module provides an implementation I<tempfile>, based on
File::Temp, for the trap's output layers. Note that you may specify
different implementations for each output layer on the trap.
See also L<Test::Trap> (:stdout and :stderr) and
L<Test::Trap::Builder> (output_layer).
=head1 CAVEATS
Using File::Temp, we need privileges to create tempfiles.
We need disk space for the output of every trap (it should clean up
after the trap is sprung).
Disk access may be slow -- certainly compared to the in-memory files
of PerlIO.
Threads? No idea. It might even work correctly.
=head1 BUGS
Please report any bugs or feature requests directly to the author.
