+Console Component
+=================
+
+Console eases the creation of beautiful and testable command line interfaces.
+
+The Application object manages the CLI application:
+
+```php
+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:
+
+```php
+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, ...
+
+Tests
+-----
+
+You can run the unit tests with the following command:
+
+    $ cd path/to/Symfony/Component/Console/
+    $ composer install
+    $ phpunit
