Alternate package source: The source to find the package(s) to install. Special sources include: ruby, webpi, cygwin, windowsfeatures, and python. To specify more than one source, pass it with a semi-colon separating the values (-e.g. 'source1;source2'). Defaults to default feeds.
Other options: Add extra options or switches as needed.
