+For example, in older versions of Django::
+
+    from django.contrib import admin
+
+    class BaseAdmin(admin.ModelAdmin):
+        actions = ['a']
+
+    class SubAdmin(BaseAdmin):
+        actions = ['b']

+Now ``actions`` follows standard Python inheritance. To get the same result as
+before::
+
+    class SubAdmin(BaseAdmin):
+        actions = BaseAdmin.actions + ['b']
