+.. _include_directive:
+
+``include``
+-----------
+
+The ``include`` directive includes configuration from an external ZCML
+file. Use of the ``include`` tag allows a user to split configuration
+across multiple ZCML files, and allows package distributors to provide
+default ZCML configuration for specific purposes which can be
+included by the integrator of the package as necessary.
+
+Attributes
+~~~~~~~~~~
+
+``package``
+
+ A :term:`dotted Python name` which references a Python :term:`package`.
+
+``filename``
+
+ An absolute or relative filename which references a ZCML file.
+
+The ``package`` and ``filename`` attributes can be used together or
+separately as necessary.
