If memory serves, the copy plugin is deprecated in favor of the dump 
plugin. Here's a small example:

         plugin: dump
         source: .
           run.wrapper: bin/run

It means there's a file in root dir (".") named run.wrapper and it 
should be copied (dumped) to bin/run in the snap, as I understand it.
