+(define-module (ice-9 rdelim))
+
+;;; Commentary:
+
+;;; This is a place holder so that '(mes test)' can use 'read-line'.
+;;; When run from Guile, 'read-line' will come from '(ice-9 rdelim)'.
+;;; When run from Mes, 'read-line' is part of the root module, but for
+;;; Guile compatibility, other modules will still have to import
+;;; '(ice-9 rdelim)'.
