What's this?

find_by_namespace(namespace, command_name = nil) public

Rails finds namespaces similar to Thor, it only adds one rule:

Command names must end with “_command.rb”. This is required because Rails looks in load paths and loads the command just before it’s going to be used.

find_by_namespace :webrat, :integration

Will search for the following commands:

"webrat", "webrat:integration", "rails:webrat", "rails:webrat:integration"

        lookup(lookups)
