"3) Would a DP for a Python artifact that contains a single python file
that prints "hello world" and which needs to be interpreted using Python 3.3 would look as follows:

Assume we have the following Python module:
helloworld/helloworld-code.py

--------
DP:

camp_version: CAMP 1.1
artifacts:
artifact_type: pyc
content:

--> module name
requirements:
requirement_type: interpreted_by
fulfillment: id:py3.3

services:
id:py3.3
characteristics:
characteristic_type: python3.3 --> interpreter to use
--------

As an aside, while writing above example I realized that the "services"
section may need to support multiple services.
Does the current spec definition have provision for that?"
