Uninstall as a command feels a little weird....
I dunno what the right solution is. My two-cents is either to punt and
only include an uninstall function as currently proposed, or for only
supporting some form of the "python setup.py uninstall" style....
But for us poor schlubs, we want you brilliant packagers to actually
come to a hard decision. If you want approval either admit you have no
solution in the PEP (and detail the issues that prevent a decision),
provide a minimally acceptable command, or expect that nobody sees the
value of what you propose....
I haven't read the PEP in detail since it's outside my area of interest
and knowledge(*), but my understanding of the goal is that the PEP is
providing an _infrastructure_ for system-level package management tools.
The uninstall function is part of that infrastructure, but since
distutils isn't a package manager itself (it's an install program),
distutils as currently organized can't really handle uninstall except
as outlined in a section you may have clipped from the above context
(ie: when setup.py from the original package is available).
A possible implementation at the python/distutils level might be to
have a 'pyuninstall' command installed (like pydoc et al are installed)
which handles uninstallation.
The question is what do the people who do real package management
(linux distribution level package management and the equivalent) think?
I'm guessing they are happy with just having the function for their
package management tools to call when needed, since (I'm hoping) they
are part of the distutils sig....
So, if my understanding of the overall goal is correct, it looks to me
like the PEP is missing a "motivation" section that talks about system
package managers.
