Hi Éric, I hadn't thought about a file that only contains the version number,
but that makes perfect sense. Here's what I propose for the PEP.
Distutils2
----------
Because the distutils2 style ``setup.cfg`` is declarative, we can't
run any code to extract the ``__version__`` attribute, either via
import or via parsing.
In consultation with the distutils-sig [9]_, two options are
proposed. Both entail containing the version number in a file, and
declaring that file in the ``setup.cfg``. When the entire contents of
the file contains the version number, the ``version-file`` key will be
used::
[metadata]
version-file: version.txt
When the version number is contained within a larger file, e.g. of
Python code, such that the file must be parsed to extract the version,
the key ``version-from-file`` will be used::
[metadata]
version-from-file: elle.py
A parsing method similar to that described above will be performed on
the file named after the colon. The exact recipe for doing this will
be discussed in the appropriate distutils2 development forum.
Cheers,
