I've mentioned my efforts on fedora previously. But like you I used a
minimal configuration. So what would be reasonable to test? I know you
mentioned building with perl and python upthread so we could possibly
test transforms. Anything else? I don't think we need to worry about all
the authentication-supporting options. XML/XSLT maybe.
