-          This option adds a `HL' target, which enables the user to decrement
-          the hoplimit value of the IPv6 header or set it to a given (lower)
-          value.
-
-          While it is safe to decrement the hoplimit value, this option also
-          enables functionality to increment and set the hoplimit value of the
-          IPv6 header to arbitrary values.  This is EXTREMELY DANGEROUS since
-          you can easily create immortal packets that loop forever on the
-          network.
