+    (description "The Java Collections Framework is the recognised standard
+for collection handling in Java.  Commons-Collections seek to build upon the
+JDK classes by providing new interfaces, implementations and utilities.  There
+are many features, including:
+
+@itemize
+@item @code{Bag} interface for collections that have a number of copies of
+  each object
+@item @code{BidiMap} interface for maps that can be looked up from value to
+  key as well and key to value
+@item @code{MapIterator} interface to provide simple and quick iteration over
+  maps
+@item Transforming decorators that alter each object as it is added to the
+  collection
+@item Composite collections that make multiple collections look like one
+@item Ordered maps and sets that retain the order elements are added in,
+  including an LRU based map
+@item Reference map that allows keys and/or values to be garbage collected
+  under close control
+@item Many comparator implementations
+@item Many iterator implementations
+@item Adapter classes from array and enumerations to collections
+@item Utilities to test or create typical set-theory properties of collections
+  such as union, intersection, and closure.
