A gem that provides credit card validation. It is basically a ruby port of the javascript credit card validator by Thomas Fuchs (madrobby) (http://github.com/madrobby/creditcard_js).

The best I could come up with was to just show you: $ atcat dbi://pg/localhost/database_name/table_name csv://table_name.csv That exports a table from Postgres into a comma separated value file. You can read from or write to: tab, csv, dbi, etc. You can opaquely treat any of those 'table of records' based sources as an opaque URI.
