The following "SisterSites.jsp" gives JSPWiki server-side support for the SisterSites standard. Just create a new file called "SisterSites.jsp" in your home dir, and drop the contents.

This should work with both 2.4 and 2.5. This will be included in 2.5.

TODO: Make a SisterSitesPlugin for actually connecting to other sites. Shouldn't be too difficult; just need to cache the information.
