First goal of this program is to learn the basic structure of a Go program. Second goal is to eliminate the need for me to go (no pun indented) to this site constantly when testing ecommerce sites we are developing.
The idea here is that we can pipe the output of this program directly to pbcoby to grap a test credit card number like so:
test_cc | pbcopy
or
test_cc -card=mastercard | pbcopy
If this proves useful I'd like to support all the of the credit card types on the site linked above.
