+The standard CIEL REPL includes Quicklisp. We remove it for packaging
+with Guix.
+
+The default Quicklisp-based build procedure removes one dependency
+relation from the system definition for ciel/repl and replaces it by
+an explicit load command using Quicklisp, as a workaround to some build
+issue. Fortunately we don't have this issue with Guix, so we go back
+to letting ASDF manage this dependency relation.
