General Information.
The algorithm was taken from the Perl script Credit Card Verifier, which was originally posted in the Matt's Script Archive. By the law, copyright of program translated in to other language belongs to the translator (me!). I have invested a lot of time into this script, and it is NOT free for any purpose but educational. If you want to use this script, please contact me.

For more information read the best JavaScript tutorial that I've ever seen, JavaScript Authoring Guide.
