Help:
  The new:extension command creates the skeleton of an extension class in the extensions directory,
  and displays the configuration to enable it.
  If you run this command without any options, it will ask you for the extension type, name and namespace.

    cecil.phar new:extension
    cecil.phar new:extension --type=generator --name=Database --namespace=MySite

  Available types: generator, twig, postprocessor, subscriber and plugin.

  To override an existing extension, run:

    cecil.phar new:extension --force
```
