Agenda items for next meeting

Improve error messages related to concretizing large DAGs that are over-constrained
- Peter: I think a heuristic approach would be useful: when you get something like "can't pick version 4.1 and 5.2", look for all the packages in the dag which enforce constraints related to that
- Greg/Todd: use xclingo to extract a description of the constraints
