This addon generates legacyexternalcommand package files of a rock.
First argument is the name of a rock, the second argument is optional
and needed when legacyexternalcommand uses another name (usually prefixed by lua-).
Files are generated with the source content of the rock and more
especially the rockspec. So, the rock is downloaded and unpacked.
