[Mediawiki-l] Wikipedia template logic

[chris muse]

We've been trying to download wikipedia pages and their template
dependencies and noticed that several pages use logic templates such as
Template:qif to help display those pages. Mediawiki 1.5.4 won't render the
logic in these templates, instead the template gets inserted verbatim. Is
there a setting in the application that turns this on that we have just
overlooked? How does Wikipedia handle the if else test clauses?

Thanks,
Chris
