That wasn't what I had in mind, although now that you mention it, it sounds
kind of handy. Not so much that people would type it directly, as that
folks who don't want their users to have to install EasyInstall, could use
it as part of their build process.
Hm. That's actually a fantastic idea. Thanks! :)

Something like that. I actually more meant that things like the current
logging verbosity would be shared, configuration files shared,
etc. However, this is actually a fantastic thing for the new idea
(allowing packages using setuptools to install dependencies), because it
means that certain kinds of arguments passed to the parent script will be
usable by the child scripts (e.g. compiler options, install locations,
Interestingly, this is what I originally set out to make setuptools do,
i.e. know about dependencies and be able to download/install them, but the
work kind of stalled as I ran into complex issues of selecting the right
platform and distribution to install. EasyInstall addressed these issues
and solved them starting from a point of view based on a totally different
use case, but seems to have found its way full circle now. :)
