lithium\console\Router
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.

/**
* Parse incoming request from console. Short and long (GNU-style) options
* in the form of `-f`, `--foo`, `--foo-bar` and `--foo=bar` are parsed.
* XF68-style long options (i.e. `-foo`) are not supported but support
* can be added by extending this class.
*
* Long options like `--foo-bar` are camelized and made available
* after parsing as `fooBar`.
