Hi: I wanted to move this tool out of the bluez project, into udev-extras. It seems to make more sense to me there as it's not really meant to be ran by the user. I'm attaching the patch as my mail server would eat it up otherwise (Exchange). Thanks, -- Mario Limonciello *Dell | Linux Engineering* mario_limonciello@xxxxxxxx
