It depends on what code. Let's say that we want to have one and only one place for the "version" value. There are two type of code in a Distutils-based project. The one that is used in setup.py to create distribution, compile extensions (I'll call it the "build code"), and the one that is installed on the target system. For the build code, if Distutils has the capability to get metadata from setup.cfg, then it would be just a matter of publishing an API for getting it as well in there. Now, if the project is installed, setup.[py/cfg] are gone, and the only place where the version is located is the PKG-INFO file. Distribute/Setuptools provides and APIs to read this PKG-INFO file and get it already. IOW, in the packages and modules of the project, this API can be used. The only concern I have is that the development mode (e.g. getting the version in the packages and modules of the project when it's not installed) supposes that the "develop" command was called (so that the PKG-INFO file is locally available). But I would definitely completely isolate setup.py code from the project' packages/modules to avoid problems.
