Hello Yuri and Albert,

Attached is a patch file to bring the KSudoku Handbook up to date. I =
diffed my edits against a copy of the index.docbook source I copied from =
invent.kde.org a day ago.

Please excuse any typos or XML errors. My XML is very rusty and I was =
unable to test the updated index.docbook file. I hope it behaves OK for =
you, Yuri.

All the best,
Ian Wadham.
