The <info>%command.name%</info> command will compile code in a new PHAR based on a variety of settings.
<comment>
  This command relies on a configuration file for loading
  PHAR packaging settings. If a configuration file is not
  specified through the <info>--config|-c</info> option, one of
  the following files will be used (in order): <info>box.json</info>,
  <info>box.json.dist</info>
</comment>
The configuration file is actually a JSON object saved to a file. For more
information check the documentation online:
