the '*' means that the argument(s) are addresses of the
form domain!user.  if the '*' is missing the address is
assumed to be an IP address.  in the example, the
'*' on the 'allow' verb is wrong; it should read

allow	63.12.0.0/16

in summary, the rule is: lines beginning with '*'
are NOT IP addresses, they are account names;
lines that do NOT begin with '*' contain IP addresses
as arguments.

i will also fix the documentation.
