How get used AdminSite in a Django-project (custom or standart)?

if I have my custom adminsite

http://dpaste.com/0ZJ77EH

To get used the adminsite I simple imported it.

from conf.admin import ProgrammerHelperAdminSite

But may exists build-in Django method, for getting used AdminSite

For example Django has useful method for getting AUTH_USER_MODEL

from django.contrib.auth import get_user_model
