Silex is hardly a &quot;micro framework&quot;, it&#x27;s basically Symfony without the configuration files. So it&#x27;s a LOT of code. I like it by the way, always hated the Spring like insanity of Symfony, but let&#x27;s not pretend Silex + all Symfony libs the framework has to import are small.<p>The irony is that for this very project, Both Silex and Symfony\Process are completely redundant, especially with PHP bloated core APIs.
