How can I load the origin templatetags (commets) when I custom comments app.

[ghost]

I follow the doc 'Customizing the comments framework' and build an custom comments app.
The doc teach me set like this:

INSTALLED_APPS = [
    ...
    'my_comment_app',
    ...
]

COMMENTS_APP = 'my_comment_app'

But I want to use the templatetags in origin app. Since 'django_comments' not add in INSTALLED_APPS , I can not load 'templatetags.comments.py' in my template. Must I copy all code from that module to my custom app? Or is there more elegent solution?

Thank for you help!

With Django 1.9+, I guess you can leverage the libraries entry in TEMPLATES backend OPTIONS.
