Well, that only doesn't give a precise description. It requires more
deep analysis. For examples, binaries have to be examined for which
libraries they're linked against. But that yet doesn't tell 
everything, eg. files that get loaded at runtime.

In the end there's no _reliable_ automatic way to do it, unless
we have some precise declaration coming from the package itself.
I'm currently working on an file classifier and dependency detector,
for use in package management and QM, but this is damned to be 
imcomplete simply due lack of information.
