Routing Component
=================

Routing associates a request with the code that will convert it to a response.

The example below demonstrates how you can set up a fully working routing
system:

```php
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Matcher\UrlMatcher;
use Symfony\Component\Routing\RequestContext;
use Symfony\Component\Routing\RouteCollection;
use Symfony\Component\Routing\Route;

$routes = new RouteCollection();
$routes->add('hello', new Route('/hello', array('controller' => 'foo')));

$context = new RequestContext();

// this is optional and can be done without a Request instance
$context->fromRequest(Request::createFromGlobals());

$matcher = new UrlMatcher($routes, $context);

$parameters = $matcher->match('/hello');
```
