+== Cascading Templates ==
+If you wish to inherit the functionality from another template & then make tweaks, you can do this by cascading templates:
+
+{{{modules/templates/MY_TEMPLATE/config.py}}}:
+{{{
+def config():
+    from templates.OTHER_TEMPLATE.config import config as OTHER_config
+    OTHER_config()
+    settings.base.system_name = T("Other System Name")
+    settings.base.system_name_short = T("Other Short System name")
+}}}
+
+{{{modules/templates/MY_TEMPLATE/controllers.py}}}:
+{{{
+# Pull a page from another template
+from templates.OTHER_TEMPLATE.controllers import other_page
+# (This coukld be subclassed if-desired)
+
+# Define your own homepage:
+class index():
+    ...
+}}}
+
+{{{modules/templates/MY_TEMPLATE/menus.py}}}:
+{{{
+from templates.OTHER_TEMPLATE.menus import S3OptionsMenu as OTHEROptionsMenu
+class S3OptionsMenu(OTHEROptionsMenu):
+    # Override those side menus which are specific.
+}}}
