+    (description
+     "This is an implementation of an ordered dictionary with @dfn{Key
+Insertion Order} (KIO: updates of values do not affect the position of the
+key), @dfn{Key Value Insertion Order} (KVIO, an existing key's position is
+removed and put at the back).  The standard library module @code{OrderedDict},
+implemented later, implements a subset of @code{ordereddict} functionality.
+Sorted dictionaries are also provided.  Currently only with @dfn{Key Sorted
+Order} (KSO, no sorting function can be specified, but a transform can be
+specified to apply on the key before comparison (e.g. @code{string.lower})).")
