I added a section here.

My code is derived from the documentation of multi plugin found here

except instead of defining separate route and multi plugins, I nest all the 
plugin defs so that only one set of $CARD,$DEV,$SUBDEV parameters are 
required. As you see in the above example, if you have fixed devices the 
setup is much less verbose.
