Hmm.. nice patch Jag, but I'm not sure that we want to fill Django up with markup engines. I'm going to mark this as wontfix, but if someone really disagrees with me, please reopen this ticket with design-decision-needed.

I would venture to say that it is a good idea to include additional markup engines:

Currently there isn't a straightforward way to add your own engines. You would have to patch django or copy the markup filter code to your project and rework it that way. This seems a bit clumsy, and in time would create duplicate efforts among various developers. What do the core developers think?

[James Bennett]

A third-party solution is already available which provides a generic system for supporting arbitrary markup schemes through template filters, so I'd be inclined to leave this at wontfix.

will not hurt, helps a lot!

Please don't reopen tickets closed wontfix, please see ​http://docs.djangoproject.com/en/dev/internals/contributing/#id1, which notes what you should do in cases where you disagree with such a decision.
