Berks upload chokes on recipe with __END__ in it


I have a recipe that has __END__ in it, and some stuff after that that I would like to keep.

The recipe is valid ruby syntax according to ruby -c. And in fact I can run the recipe in Test Kitchen with kitchen converge. However, when I try and upload it with berks upload I get an error that the __END__ line is a ruby syntax error.

$ berks upload

Do I have to get rid of the __END__ and everything after it in order to use Berkshelf?
