Before Composer, we downloaded packages manually, one by one. Now we do it in Composer update. That way you’ll update a dependency from Symfony 3.0 to Symfony 4.0. How do you fix BC breaks in your code? Manually, one change after another, file by file. In a non-PHP world, lazy Google and Facebook folks automated such work with tools. What about PHP? With AST from [nikic/php-parser](https://github.com/nikic/PHP-Parser) this is now possible in PHP as well. I’ll show you how Rector can handle 80 % of boring upgrades for you. I can help with Symfony, Sylius, Twig, Nette, Doctrine and PHPUnit code.
