I haven't looked at it yet, but I am skeptical. Do you think
it will do what I want? XML is just barely human readable.
It tends to be slow. It is OK for a least common denominator,
but you can almost always do better.
Yes, SIXX is very slow and not recommended for daily use. It didn't
work on it for about a year and I suggest to use it solely to move
wikis from one image to another one.
