Please review the attached. Modifications to
tools/dev/mk_manifest_and_skip.pl and lib/Parrot/Manifest.pm. Tso
additional test files in t/manifest/.
In reviewing the patch, I recommend that you first run
tools/dev/mk_manifest_and skip.pl before running t/manifest/*.t. In
that way, you will be starting from a presumptively correct MANIFEST.
The interface to Parrot::Manifest has changed since last weekend.
However, that will not matter assuming that all you ever do is call:
perl tools/dev/mk_manifest_and_skip.pl. *That* is unchanged.
Thank you very much.
