# I'm having problem to setup a nice approach to config login credentials
# for different sites. I have different classes/strategies to login on
# sites and I wanna config them at the same place (seems wise).

# The sites can have different variables needed for the login. Some needs
# username/password and some uses api-keys only.

# This is the first approach but I don't like it. Any suggestions?

module Foobar

    # Helper method from active support to set module attributes
    mattr_accessor :credentials
    @@credentials = {}

    def self.setup
        yield self
    end

end

Foobar.setup do |config|

    config.credentials = {
        :my_site = {
            :username => 'foo',
            :password => 'bar'
        }
        :my_other_site = {
            :user_id => '123',
            :api_key => 'abc123'
