What are the advantages and disadvantages of using Symfony Console for handling command line arguments in PHP scripts?

Symfony Console is a powerful library for handling command line arguments in PHP scripts. It provides a clean and structured way to define commands, options, and arguments for your CLI applications. One advantage of using Symfony Console is that it abstracts away the complexity of parsing and validating command line input, making it easier to build robust CLI applications. However, one disadvantage is that it may introduce a dependency on the Symfony framework, which could be overkill for smaller projects. 

// Example code using Symfony Console to handle command line arguments
require 'vendor/autoload.php';

use Symfony\Component\Console\Application;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

$application = new Application();

$application->register('greet')
    ->addArgument('name', InputArgument::REQUIRED, 'Your name')
    ->addOption('yell', null, InputOption::VALUE_NONE, 'Yell it out loud')
    ->setDescription('Greet someone')
    ->setCode(function (InputInterface $input, OutputInterface $output) {
        $name = $input->getArgument('name');
        $output->write("Hello, $name");

        if ($input->getOption('yell')) {
            $output->write('!', true);
        }
    });

$application->run();
