+     "This package provides an implementation of SRFI 146 for Guile.
+SRFI 146 defines datastructures that implement mappings (finite sets
+of associations consiting of a key and a value).  Two types of
+mappings are defined: One using a comparator to define an order on the
+keys and another using a hash function on the keys.  The
+datastructures and procedures are by default purely-functional.  This
+package re-uses the SRFI sample implementation that is based on
+red-black trees and Hash Array Mapped Trie (HAMT).")
