Usage examples

Apply :admin_flag Role strategy to User model using default roles :admin and :guest (default)

Apply :admin_flag Role strategy to User model using default roles and extra role :author

$ rails g data_mapper:roles_migration User --strategy admin_flag --roles author

Apply :one_role Role strategy to User model without default roles, only with roles :user, :special and :editor

Note on Patches/Pull Requests

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
