The User Extensions Manager allows the application developer to augment the
executive by allowing them to supply extension routines which are invoked at
critical system events. The directives provided by the User Extensions Manager
are:

* :ref:`InterfaceRtemsExtensionCreate` - Creates an extension set.

* :ref:`InterfaceRtemsExtensionDelete` - Deletes the extension set.

* :ref:`InterfaceRtemsExtensionIdent` - Identifies an extension set by the
  object name.
