+Console Component
+=================
+
+Console eases the creation of beautiful and testable command line interfaces.
+
+The Application object manages the CLI application:
+
+    use Symfony\Component\Console\Application;
+
+    $console = new Application();
+    $console->run();
+
+The ``run()`` method parses the arguments and options passed on the command
+line and executes the right command.
+
+Registering a new command can easily be done via the ``register()`` method,
+which returns a ``Command`` instance:
+
+    use Symfony\Component\Console\Input\InputInterface;
+    use Symfony\Component\Console\Input\InputArgument;
+    use Symfony\Component\Console\Input\InputOption;
+    use Symfony\Component\Console\Output\OutputInterface;
+
+    $console
+        ->register('ls')
+        ->setDefinition(array(
+            new InputArgument('dir', InputArgument::REQUIRED, 'Directory name'),
+        ))
+        ->setDescription('Displays the files in the given directory')
+        ->setCode(function (InputInterface $input, OutputInterface $output) {
+            $dir = $input->getArgument('dir');
+
+            $output->writeln(sprintf('Dir listing for <info>%s</info>', $dir));
+        })
+    ;
+
+You can also register new commands via classes.
+
+The component provides a lot of features like output coloring, input and
+output abstractions (so that you can easily unit-test your commands),
+validation, automatic help messages, ...
