Does Django have a template tag that can detect URLs and turn them into hyperlinks?

Django has the urlize template filter which will automatically detect both URLs and email addresses and turn them into the appropriate hyperlinks.

The docs there are actually a little thin, so I recommend also reading the docstring in the source for the urlize function for more information.
