 ## Specifically, use the address-comparison operator OPT (typically `-s' or
-## `-d') to match the addresses of NOT, writing the rules to the chain
-## BASESUFFIX.  If we find a match, dispatch to WIN-CLASS, where CLASS is
-## the class of the matching network.  In order to deal with networks
-## containing negative address ranges, more chains may need to be

-## with NEXT.  All of this happens on the `mangle' table, and there isn't
-## (currently) a way to tweak this.
