Well, the question is which should. E.g., if you install PasteScript, then Paste, then remove PasteScript, PasteScript should leave paste/__init__.py since Paste also needs it. In practice, I tend to notice files like this are just left around by packagers. I don't think that would be appropriate at all in this situation, though (it would mean there would still be an importable "paste" even though there'd be nothing in it). > I think that there is something wrong in the installation if > it overwrites each other's files during the process. This is why Eggs have their namespace package support, but it relies on the packages being installed in separate hierarchies even though they share the same package space. If Phillip can fix that, then great, we should all be happy ;) Yet another option would be to make Paste a requirement for PasteDeploy and PasteScript, and rely on Paste installing paste/__init__.py Namespace packages *are* rather annoying, I'll admit. If I knew when I first wrote them how I wanted paste.* factored into three packages, I probably wouldn't have used a namespace package. The only real reason I see for it is legacy package names, or when you really really like hierarchy (and I don't). The issue with installing as an egg is that either you have to have postinstall scripts handle easy-install.pth (or rpm-install.pth or something), or you have to handle the fact that no egg will be installed by default. But otherwise you can just install an egg instead of using --single-version... -- and I don't know if there's really a reason not to do that at this time. -- Ian Bicking / [EMAIL PROTECTED] / http://blog.ianbicking.org _______________________________________________ Distutils-SIG maillist - [email protected] http://mail.python.org/mailman/listinfo/distutils-sig
