By providing a [metadata] section in your setup.cfg that contains them.

The idea is that a project can provide a compatibility for d2 without
removing the one for d1 - so pip and easy_install still work :

- d1/setuptools/distribute : setup.py
- d2: setup.cfg

Then, by using distutils2 register command, you can push the Metadata
1.2 to pypi.

This week end we're having a sprint where we will document this
process. We're also planning to provide a script to
automate the creation of [metadata] by running setup.py to make it easier.
