Thanks Guys :) Thanks to Paulus for miscellaneous tidy ups, some largish chunks of much nicer and/or completely new code and (perhaps most uniquely) having the patience to sit down and explain why and where he'd changed stuff. Tip 'o the hat to IBM (and previously Linuxcare :) for supporting staff in their work on open source projects.
