+synopsis: "Alcotest is a lightweight and colourful test framework"
+description: """
+Alcotest exposes simple interface to perform unit tests. It exposes
+a simple TESTABLE module type, a check function to assert test
+predicates and a run function to perform a list of unit -> unit
+test callbacks.
+
+Alcotest provides a quiet and colorful output where only faulty runs
+are fully displayed at the end of the run (with the full logs ready to
+inspect), with a simple (yet expressive) query language to select the
+tests to run.
