+.Sh DESCRIPTION
+.Nm
+is a tool to attach and detach slave network devices to a bonding device.
+A bonding device will act like a normal Ethernet network device to the kernel,
+but will send out the packets via the slave devices using a simple round-robin scheduler.
+This allows for simple load-balancing,
+identical to "channel bonding" or "trunking" techniques used in switches.
+.Pp
+The kernel must have support for bonding devices for
+.Nm
+to be useful.
+.Sh OPTIONS
+.Bl -tag -width indent
+.It Fl a, -all-interfaces
+Show information about all interfaces.
+.It Fl c, -change-active
+Change active slave.
+.It Fl d, -detach
+Removes slave interfaces from the bonding device.
+.It Fl f, -force
+Force actions to be taken if one of the specified interfaces appears not to belong to an Ethernet device.
+.It Fl h, -help
+Display a help message and exit.
+.It Fl u, -usage
+Show usage information and exit.
+.It Fl v, -verbose
+Print warning and debug messages.
+.It Fl V, -version
+Show version information and exit.
+.El
+If not options are given, the default action will be to enslave interfaces.
+.Sh EXAMPLE
+The following example shows how to setup a bonding device and
+enslave two real Ethernet devices to it:
+.Bd -literal
+# modprobe bonding
+# ifconfig bond0 192.168.0.1 netmask 255.255.0.0
+# ifenslave bond0 eth0 eth1
