 All paths are expected to exist. If you need some glob functionality, you can do it in your config file and pass the expanded list to e.g. `ignoreErrorsOnPaths`.
 
 ### Detecting classes from non-php files:

+Some classes might be used only in your DIC config files. Here is a simple way to extract those:

 Another approach for DIC-only usages is to scan the generated php file, but that gave us worse results.

 - Extension dependencies are not analysed (e.g. `ext-json`)
