Shouldn't this new module be named "pkglib" to be in line with
the naming scheme used for all the other utility modules, e.g. httplib,
imaplib, poplib, etc. ?

Are you saying that the installation of setuptools in Python 2.3
and 2.4 will then overwrite the standard pydoc included with
those versions ?

I think that's the wrong way to go if not made an explicit
option in the installation process or a separate installation
altogether.

I bothered by the fact that installing setuptools actually changes
the standard Python installation by either overriding stdlib modules
or monkey-patching them at setuptools import time.

Add setuptools to the stdlib ? I'm still missing the PEP for this
along with the needed discussion touching among other things,
the change of the distutils standard "python setup.py install"
to install an egg instead of a site package.
