 #  = DHCPv4 Module
 #
-#  The `dhcpv4` module is useful only for `xlat`. To use it,
-#  put `dhcp` into the `instantiate { ... }` section.
-#
-#  `%{dhcp_options:<Attribute-ref>}` may be used to decode
-#  DHCP options data included in RADIUS packets by vendors
-#  of DHCP to RADIUS gateways.
-#
-#  This is known to work with the following VSAs:
-#
-#  [options="header,autowidth"]
