[Zope] How can a document know its own URL?

Can anyone tell me how to use DTML to get at the URL for the document being displayed? I want to display the URL of the document being displayed inside of the document being displayed. Something like: <b> You are now viewing the following URL: <dtml-var Some_DTML_var> </b> Similar to the <dtml-var title_or_id> var, but for the whole URL not just the documents name or title... I've tried looking at the mailing list archives, but it is either not there or my search criteria are not as accurate as they should... --- Brendon Grunewald 70South: The no1. source for Antarcticles.
