+-- interface and the internal interface that the solver actually
+-- expects. There are a number of type conversions to perform: we
+-- have to convert the package indices to the uniform index used
+-- by the solver; we also have to convert the initial constraints;
+-- and finally, we have to convert back the resulting install
+-- plan.
