This gem is a port of Perl's Data::Faker library that generates fake data.
It comes in very handy for taking screenshots (taking screenshots for my project, Catch the Best was the original impetus for the creation of this gem), having real-looking test data, and having your database populated with more than one or two records while you're doing development.

Just set Faker::Config.locale to the locale you want, and Faker will take care of the rest.
If your locale doesn't already exist, create it in the \lib\locales\ directory and you can then override or add elements to suit
