# version, so instead we include the `static` template tag ourselves.
# When 1.3 becomes unsupported by REST framework, we can instead start to
# use the {% load staticfiles %} tag, remove the following code,
# and add a dependancy that `django.contrib.staticfiles` must be installed.
# Note: We can't put this into the `compat` module because the compat import
# from rest_framework.compat import ...
# conflicts with this rest_framework template tag module.
