Massimiliano Culpo 48eb50921a concretizer: added rules and code for externals ... Generate facts on externals by inspecting packages.yaml. Added rules in concretize.lp Added extra logic so that external specs disregard any conflict encoded in the package. In ASP this would be a simple addition to an integrity constraint: :- c1, c2, c3, not external(pkg) Using the the Backend API from Python it requires some scaffolding to obtain a default negated statement.		2020-11-17 10:04:13 -08:00
