How about

Extensions are fields that start with a pypi-registered name followed by a hyphen. A file that contains extension fields declares them with Extension: name : Extension: pypiname pypiname-Field: value

The repetition seems rather annoying. Compare the two section based variants I just posted to:

Extension: wheel
wheel-Version: 0.9
wheel-Packager: bdist_wheel-0.1
wheel-Root-Is-Purelib: true

It does have the advantage that tools for manipulating the format can remain dumber, but that doesn't seem like that much of an advantage, especially since any such benefit could be eliminated completely by just switching to a completely standard ConfigParser format by putting the PEP defined settings into a [python] section.

Cheers, Nick.
