-Driver: comedi_bond
-Description: A driver to 'bond' (merge) multiple subdevices from multiple
-	     devices together as one.
-Devices:
-Author: ds
-Updated: Mon, 10 Oct 00:18:25 -0500
-Status: works
-
-This driver allows you to 'bond' (merge) multiple comedi subdevices
-(coming from possibly difference boards and/or drivers) together.  For
-example, if you had a board with 2 different DIO subdevices, and
-another with 1 DIO subdevice, you could 'bond' them with this driver
-so that they look like one big fat DIO subdevice.  This makes writing
-applications slightly easier as you don't have to worry about managing
-different subdevices in the application -- you just worry about
-indexing one linear array of channel id's.
-
-Right now only DIO subdevices are supported as that's the personal itch
-I am scratching with this driver.  If you want to add support for AI and AO
-subdevs, go right on ahead and do so!
-
-Commands aren't supported -- although it would be cool if they were.
-
-Configuration Options:
-  List of comedi-minors to bond.  All subdevices of the same type
-  within each minor will be concatenated together in the order given here.
