-.SH DESCRIPTION
-The Internet Software Consortium DHCP Relay Agent, dhcrelay, provides a
-means for relaying DHCP and BOOTP requests from a subnet to which
-no DHCP server is directly to one or more DHCP servers on other
-subnets.
-.SH OPERATION
-.PP
-The DHCP Relay Agent listens for DHCP requests on all interfaces
-attached to a host, or only on those interfaces specified on the
-command line with the
-.I -i
-flag.   When a query is received, it forwards it to the list of DHCP
-servers specified on the command line.   When a reply is received, it
-is broadcast or unicast on the network from whence the original
-request came.
-.PP
-It is possible to specify a set of interfaces on which dhcrelay will
-listen, so that if dhcrelay is connected through one interface to a
-network on which there is no DHCP server, but is connected on another
-interface to a network on which there is a DHCP server, it will not
-relay DHCP and BOOTP requests from the network on which the server
-exists to that server.   This is an imperfect solution.
-.SH COMMAND LINE
-.PP
-The names of the network interfaces that dhcrelay should attempt to
-configure may be specified on the command line using the
-.I -i
-option.  If no interface names
-are specified on the command line dhcrelay will identify all network
-interfaces, elimininating non-broadcast interfaces if possible, and
-attempt to configure each interface.
-.PP
-If dhcrelay should listen and transmit on a port other than the
-standard (port 67), the
-.B -p
-flag may used.  It should be followed by the udp port number that
-dhcrelay should use.  This is mostly useful for debugging purposes.
-.PP
-Dhclient will normally run in the foreground until it has configured
-an interface, and then will revert to running in the background.
-To run force dhcrelay to always run as a foreground process, the
-.B -d
-flag should be specified.  This is useful when running dhcrelay under
-a debugger, or when running it out of inittab on System V systems.
-.PP
-The name of at least one DHCP server to which DHCP and BOOTP requests
-should be relayed must be specified on the command line.
-.PP
