lithium\console\Router

class

The Router class uses an instance of lithium\console\Request, which represents an incoming command-line invocation, to parse the correct command, and sub-command(s) and parameters, which are used by lithium\console\Dispatcher to load and execute the proper Command class.

	 * Long options like `--foo-bar` are camelized and made available
	 * after parsing as `fooBar`.
