I didn't think at all about this because I am not looking at how to
resolve dependency problems during an install. I am trying to build
something that looks at all the rpms available and answers by itself
to questions like: Find among these 20 email clients, 15 browser, 12
text editors, 20 news clients..... (all end user applications) the
combination requiring the smallest number of RPMs and HD megabytes.

It is still a problem based on dependencies, but (in my eys at least)
seemed enough different from installers tasks to justify a different
approach, and hopefully to have been already solved by somebody: the
difference being in the fact that the installer must "only" find a
solution good enough (no conflicts/missing part, and space
requirements smaller than the current hard disk), I wanted to find the
best possible solutions with stock RPMs regardless of the HD size.

Another output I'd like from it is to say: you need to install this
RPM, but only 50% of its files are actually needed by other packages,
you can safely remove the rest.

What do you think?
