Hmm... I guess it probably also matters whether the files in
question are actually directories.  For instance, examining the
output from "rpm -ql" for some installed packages on a running
system, I observe that all of the following packages list the
path /usr/share/applications in their output:


I assume it would be a mistake to conclude that all of these
packages therefore conflict with each other.

Let's say I'm writing a C program that takes as input a bunch
of RPM files.  My goal is to examine the packages using RPM
library calls, and produce output indicating which packages
conflict with each other.  What would be the preferred way of
doing this?
