+``BTrees``:  scalable persistent components
+===========================================
+
+This package contains a set of persistent object containers built around
+a modified BTree data structure.  The trees are optimized for use inside
+ZODB's "optimistic concurrency" paradigm, and include explicit resolution
+of conflicts detected by that mechannism.
+
+Please see the Sphinx documentation (``docs/index.rst``) for further
+information.
