Existing SHA1 digests verified, all found to be the same on the
machine holding the existing distfiles (morden). Existing SHA1
digests retained for now as an audit trail.
This module calculates the Modulus 10 Double Add Double checksum,
also known as the LUHN Formula. This algorithm is used to verify
credit card numbers and Standard & Poor's security identifiers such
as CUSIP's and CSIN's.
You can find plenty of information about the algorithm by searching
the web for "modulus 10 double add double".
