I have most of the stuff reworked except for the address, gateway, 
netmask, and prefix code.  Getting all of those balanced so they work 
correctly is a bit tricky..

1.  For <route>, I am requiring that both address= and gateway= be 
specified with address='0.0.0.0' and address='::' being valid 
addresses.  For IPv4, netmask='0.0.0.0' works correctly but prefix=0 
does not.

For IPv4, address='0.0.0.0' results in a default route.  I am not sure 
what all these extra default routes are going to do to things but lets 
not get in the way of the experimenter.

For IPv6, this address='::', prefix='0' is a slightly different matter 
as default routes are usually handled differently.  I am going to go 
ahead and implement it but I am not sure it is a good idea.  "Normally," 
if you do not specify a prefix for IPv6, the default is 64.  But if you 
do specify one, then it will be used.

It is getting real close and it should be ready "real soon now" ;))
