module Rails::Command

:nodoc:

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

Will search for the following commands:

find_by_namespace :webrat, :integration

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

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

def find_by_namespace(namespace, command_name = nil) # :nodoc:
  lookups = [ namespace ]
  lookups << "#{namespace}:#{command_name}" if command_name
  lookups.concat lookups.map { |lookup| "rails:#{lookup}" }
  lookup(lookups)
  namespaces = subclasses.index_by(&:namespace)
  namespaces[(lookups & namespaces.keys).first]
end
