"""Determine the Python requirements files.

The script returns the requirements files as space separated string:

$ requirements_files.py
requirements/requirements.txt requirements/requirements-dev.txt

The script takes an optional template argument that is used to wrap each requirements filename. For example:

$ requirements_files.py "-r %s"
-r requirements/requirements.txt -r requirements/requirements-dev.txt
