+
+NOTES
+       The program does not configure network interfaces direct-
+       ly.  It runs scripts defined by the SERVICE variable in
+       the network configuration file.
+
+       The configuration files must have the following environ-
+       ment variables set:
+
+       IFACE   - The interface to configure, e.g. eth0.  It must
+                 be available in /sys/class/net.
+
+       SERVICE - The service script to run to bring up the inter-
+                 face.  Standard services are ipv4-static and
+                 ipv4-static-route.  Other services such as dhcp
+                 or bridge may be installed.  This value may
+                 be a list of services when the interface is a
+                 compound device such as a bridge.
+
+       ONBOOT  - If set to 'yes', the specified interface is
+                 configured by the netowrk boot script.
+
+       GATEWAY - The default IP address to use for routing if
+                 the destination IP address is not in a static
+                 route or on a local network, e.g., 192.168.1.1.
+                 For secondary IP addresses on an interface, this
+                 parameter should not be specified.  If the service
+                 is ipv4-static-route, this parameter must NOT
+                 be set.
+
+       STATIC_GATEWAY - The default IP address to use for routing
+                 when setting a static routing address.
+
+       INTERFACE_COMPONENTS - A list of component interfaces
+                 only needed for a compound device such as a bridge.
+                 This list is normally a single value, e.g. eth0,
+                 for use with a virtual host such as kvm.
+
+       Other paramters that are service specific include:
+
+       ipv4-static
+
+         IP        - The IP address of the interface,
+                     e.g. 192.168.1.2.
+
+         PREFIX    - The number of bits that specify the network
+                     number of the interface.  The default, if not
+                     specified, is 24.
+
+         LABEL     - The label to be assigned to the interface.
+                     This is normally specified for assigning
+                     additional IP addresses to a network
+                     device.  Example: eth0:2 (optional)
+
+         BROADCAST - The brodcast address for this interface,
+                     e.g 192.168.1.255.  If not specified,
+                     the broadcast address will be calculated
+                     from the IP and PREFIX.
+
+       ipv4-static-route
+
+         TYPE    -  The type of route, typically 'default',
+                    'network', 'or host'.
+
+         IP      -  The IP address for a network or host, if the
+                    TYPE is not 'default'.
+
+         PREFIX  -  The prefix for the associated IP address.
+
+         STATIC_GATEWAY - The IP address for a network route.
+
+         SOURCE  -  The source IP address to prefer when sending
+                    to the destinations covered by the specified
+                    route. (optional)
+
+       dhcp/dhclient
+
+         DHCP_START - Optional parameters to pass to the dhcp client
+                      at startup.
+
+         DHCP_STOP  - Optional paremeters to pass to the dhcp client
+                      at shutdown.
+
+         PRINTIP    - Flag to print the dhcp address to stdout
+
+         PRINTALL   - Flag to print all obtained dhcp data to stdout
+
+       bridge
+
+         IP_FORWARD - An optional flag to enable the system to forward
+                      inbound IP packets received by one interface to
+                      another outbound interface.
+
+         STP        - Set bridge spanning tree protocol.  Default is no.
