+%description
+mccs (which stands for Multi Criteria CUDF Solver) is a CUDF problem
+solver developed at UNS during the European MANCOOSI project.
+
+This project contains a stripped-down version of the mccs solver,
+taken from snapshot 1.1, with a binding as an OCaml library, and
+building with jbuilder.
+
+The binding enables interoperation with binary CUDF data from the
+OCaml CUDF library, and removes the native C++ parsers and printers.
