+  <longdescription lang="en">
+    The datastructures package aims at providing standard
+    datastructures, consolidating existing code and improving on it, in
+    particular in view of HPC-GAP.
+
+    The datastructures package consists of two parts: interface
+    declarations and implementations. The goal of interface declarations
+    is to define standard interfaces for datastructures and decouple
+    them from the implementations. This enables easy exchangability of
+    implementations, for example for more efficient implementations, or
+    implementations more suited for parallelisation or sequential use.
+
+    The datastructures package declares interfaces for the following
+    datastructures:
+
+      * queues
+      * doubly linked lists
+      * heaps
+      * priority queues
+      * hash tables
+      * dictionaries
