Hi Freddie,
That's incredibly quick, and exactly what was needed.  If you want the XML
displayed as more readable tables, I have written a Python script for
generating wiki tables from XML.  I'll have to check if it still works, but
I guess the extension would have to be written in PHP, or can you embed
Python extensions?  The Python version uses the xml.dom.minidom package so
it would depend on whether PHP has similar XML parsing libraries.

Also, is it possible to shift the CVS and Bugzilla servers to the new web
server?  I guess it would be nice if everything were self-contained.
Perhaps that should be a discussion item next week.
