[Distutils] EasyInstall: List of installed packages

[Paul Moore]

Is there a way of asking EasyInstall "what packages are installed"?
Without that, I can't see myself moving away from bdist_wininst.

I know that a registry of installed packages starts to move away from
the "easy" bit of "EasyInstall", but to be honest, EasyInstall is no
easier *for me* than double clicking on a bdist_wininst executable.

Paul.
