PEP 376 doesn't want to go that far anyway. The uninstall API is just
API that can be used to remove *one* distribution. So if there's a
it should be the simplest thing possible.
The goal of PEP 376 is to provide tools for installers/uninstallers to
work with a site-package directory,
not a full featured uninstaller.
I am starting to think when reading back this whole thread, that
there's a missing API:
a way to read and write arbitrary files in the egg-info directory of
an installed distribution.
This would allow third-party tools to have their own extra metadata
That is, IIRC, what Jim proposed a while ago when he said that we
should have a way
to define arbitrary metadata for distributions.
