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, ...
