Currently, it is assumed that tests has no subdirectories.  This has
been raised before, with the result that the Perl gurus were not sure
how to portably recursively copy a directory (apparently, Perl/CPAN has
rmtree, but no cptree?).

I think if you simply want to find a file in a dir tree, you could have
your test code create the tree first.
