-Ordering of Extensions
-----------------------
-
-.. caution ::
-
-  The order in which extensions are initially loaded is **different** to the order that their plugins are run.
-
-The order in which extensions are initially loaded is as follows:
-
-1. System plugins (in setup.py under ``ckan.system_plugins``).
-
-2. In order of the plugins specified in the config file: ``plugins =``.
-
-3. If more than one module has a plugin with the same name specified in the config, then all those are loaded, in the order the modules appear in ``sys.path``.
-
-The order that a plugins are run in, for example the order that IRoutes extensions have their ``before_map`` method run, is alphabetical by the plugin class.
-
-e.g. here is the order for these four extensions: ``<Plugin DguInventoryPlugin>``, ``<Plugin FormApiPlugin>``, ``<Plugin StatsPlugin>``, ``<Plugin WalesThemePlugin>``
-
-(This alphabetical ordering is done by ``pyutilib.component.core:ExtensionPoint.extensions()``)
