I've included the new-and-improved version, which runs in a couple of seconds....

When I type "urpmf --media main-cooker,contrib-cooker --provides --obsoletes" at a command line, I get back a usage error from urpmf. I was hoping there was some way to tell urpmf to operate on everything (or at least operate on this list of files), but leaving the package name off doesn't seem to do it.

I found the following: > http://sourceforge.net/projects/pexpect/ Yeah, I meant "is there actually no python-expect or python-pexpect package for Mandrake," but I wasn't very clear. I've since found that drakian provides a binary-only (alien'd) python-expect for python-2.1, but that's not exactly what I want.... Anyway, I have the latest versions of pexpect, python-expect, and ExpectPy; making packages for them should be trivial. In my opinion, pexpect is the coolest (it's pure python, and it's tiny, it's just about as efficient as the others, and it handles the 95% most common uses for expect exactly like the real thing), but it might be nice to have python-expect or ExpectPy as well (since they actually wrap expect, they handle 100% of all uses exactly like the real thing--and, if anyone cares, they work with python 2.1). > > 6.
