=head1   mkrrbc

Make node definitions for AMMs and Switches (one each per bladecenter)

 mkrrbc -C <cu letter> -L < start Rack number for CU> -R <startrange,endrange>     (add) 
 mkrrbc -d -C <cu letter> -R <startrange,endrange> (delete)

./mkrrbc -C d -L 2 -R 1,60

will run commands such as:
   nodeadd bcd60 groups=mm,cud,rack16
   nodeadd swd60 groups=nortel,switch,cud,rack16

and build nodelist entries that looks like this:
     "bcd60","mm,cud,rack16",,,
     "swd60","nortel,switch,cud,rack16",,,
