I noticed that "--source ..." might need to be updated to "--add-source" as "--source" is not a valid option name. As these are part of a downloaded package, the sources may need to be updated so that the script runs properly. Can you please check this? There is an existing pull request from back in August that fixes this, but has not been reviewed. #114
