* Previously, you could just specify a SRC directly
  after './extract-files', and it would work, but
  now, the arg '-p/--path' is required for the same

  doesn't match any of the args that we care about
* Make the ordering of the cases alphabetical

* This was always the default behaviour and doesn't require

* Allows extracting only a specific section from proprietary-files.txt
