OK. I've attached two additional patches below. I don't really understand how the *.def files work, so I'm just guessing about what needs to be changed. Thanks to Josh Berkus and Kris Jurka for looking over the documentation patch, which just adds descriptions of the two new functions. I apologise in advance if I've missed anything. -- ams
