     `cached` flag activates caching. This can be used to optimize performance
     if no changes are expected on the filesystem after the source was created.
     This is usually the case with static generation (as opposed to dynamic
     preview).
 
     If `settings.ini` in the source contains `[paths]` section with an
     `additional-paths` key that contains the list of additional root folders,
     `MultiSource` will be instantiated and its bases will be the original
     source plus an additional source for each additional root folder.
