 operation objects.  New operations can be added to the ``op.`` namespace,
 including that they are available in custom autogenerate schemes.  fixes #302
 - The internal system for autogenerate been reworked to build upon the
 extensible system of operation objects present in #302. A new customization
 hook process_revision_directives is added to allow manipulation of the
 autogen stream.  Fixes #301

+These are some of the constructs used to generate migration
+instructions.  The APIs here build off of the :class:`sqlalchemy.schema.DDLElement`
+and :ref:`sqlalchemy.ext.compiler_toplevel` systems.
+
+For programmatic usage of Alembic's migration directives, the easiest
+route is to use the higher level functions given by :ref:`alembic.operations.toplevel`.
