Built-in comment system

[thelaughingman]

>From looking around on the Django site, it appears that there is a
built in comment system, but as far as I can tell it is undocumented,
does anyone have any pointers on how to get started using it?  I am
building my own blog system, as I'm sure many Django users have, and I
dont really want to re-invent the wheel (commenting system) if I don't
have to.  Thanks.
