I'm coming in late and breaking threading, but wanted to reply to Tarek's original email:

- easyinstall is going to be deprecated ! use Pip ! Cool!  I wouldn't have written pip if I didn't think it would improve substantially on easyinstall. Incidentally (because I know people get really enthused about this) Carl Meyer just contributed a feature to pip to do atomic uninstallation.

Yes I saw that, it's great. And he is now involved in PEP 376 work so Pip could eventually become the first PEP 376 compliant installer/uninstaller.

Someone mentioned that easyinstall provided some things pip didn't; outside of multi-versioned installs (which I'm not very enthusiastic about) I'm not sure what this is?

Basically what you've listed on Pip front page I think, like 'not tested under windows' But I don't see any blocking point besides some testing, to move from easy_install to pip, and the deprecation of multi-versioned feature seem to go in the direction of the community.

 - distribute.index: that's packageindex and a few other things. everything required to interact with PyPI. We will promote  its usage and see if Pip wants to use it as a basis. This is a little tricky.  Primarily because there's a fair amount of logic involved in the indexing (going around to different URLs, parsing links, finding stuff).  So long as there is logic, something can go wrong -- often not in the package itself, but simple user error (e.g., it doesn't look where the user thinks it should, or a link is malformed, etc).  Because of this, and as a general design goal of pip, I want to show as much as I can about what it is doing and why. This is primarily tied into pip's logging system (which is oriented towards command-line output, and isn't the standard logging system). Also it tracks why it got to a certain links.  These are the two things I can think of where the index code in pip is tied to pip, and why it would be hard to use an external system.

OK. Maybe this particular package could be used by another tool that needs to work with PyPI. It will also include a set of APIs that corresponds to PyPI XMLPRC services.
