Not really.. but you wouldn't want to do that anyhow. You'll want to perform a sort of 'weak' selection that doesn't go into the problem resolver. If you look at the markinstall function you can see how that is done. Call mark install then process suggests/recommends for that package similarly. > b.

Dpkg is only used as a way to install .debs, all selection and ordering is done internally. > c. Is there anything for handling "Priority" in this regard? Priority is a variable that is available per-package, but it plays no role in dependency selection. > d. Where is the interface to the library equivilant to apt-cache <some > option> likely to be found? Read the apt-cache source? It's pretty short most of it and is one of the better example programs. I had a nice email on this subject but I keep loosing it.. Jason
