 * README for the guessnet examples

I've tried to reimplement using guessnet the other network detection tools
found in Debian.  Here are the results:

 - laptop-netconf
   It's where guessnet was taken from, and it should have been fully
   reimplemented.

 - divine and intuitively
   This is not yet possible, since they allow checking for IP address without
   ensuring that they match a given MACaddress.
   This check method is not supported by guessnet, and I don't plan to add it
   unless I receive explicit requests to do so.


I've included the getmac script to easily get the macaddress for a given remote
network interface.
