**
** Parse all entries in the BLOB table that are believed to be non-data
** artifacts and report any errors.  Run this test command on historical
** repositories after making any changes to the manifest_parse()
** implementation to confirm that the changes did not break anything.
**
** Options:
**
**   --limit N            Parse no more than N artifacts before stopping
**   --wellformed         Use all BLOB table entries as input, not just
**                        those entries that are believed to be valid
**                        artifacts, and verify that the result the
**                        manifest_is_well_formed() agrees with the
**                        result of manifest_parse().
