DWiki now supports generating links to URLs on the wiki's web server that are outside the DWiki itself. These are written as links in the format <...> and have to happen inside [[...]]. For example:

See [[the root of this web server|</>]].

generates a link to the DWiki's web server's root, which is all but certain to be outside the DWiki space if you're running DWiki as a CGI-BIN.
