Adding DMDScript to dub

[Walter Bright via Digitalmars-d]

Dmitry Olshansky has graciously ported DMDScript (a Javascript engine written in 
D) to D2.

  https://github.com/DigitalMars/DMDScript
I have been trying to get it into dub, but have been stalled by the following 
when I attempt to register:

  Repository owner: DigitalMars
  Repository name: DMDScript


it says in red:

  Package names may not be empty. Check dub.json.


What does that mean? There is no "package name" field in the dub.json file.
