+is useful in biology.  Examples include Sequence objects, Alignment objects
+and database searching objects.  These objects not only do what they are
+advertised to do in the documentation, but they also interact - Alignment
+objects are made from the Sequence objects, Sequence objects have access to
+Annotation and SeqFeature objects and databases, Blast objects can be
+converted to Alignment objects, and so on.  This means that the objects
+provide a coordinated and extensible framework to do computational biology.")
