+.Sh DESCRIPTION
+The
+.Nm
+utility is a network client for GEOM Gate class.
+It is responsible for creation of
+.Nm ggate
+devices and forwarding I/O requests between
+.Nm geom_gate.ko
+kernel module and
+.Xr ggated 8
+network daemon.
+Available commands:
+.Bl -tag -width ".Cm destroy"
+.It Cm create
+Connect to given
+.Xr ggated 8
+daemon and create a
+.Nm ggate
+provider related to the given remote file or device.
+.It Cm rescue
+If
+.Nm
+process died/has been killed, you can save situation with this
+command, which creates new connection to the
+.Xr ggated 8
+daemon and will handle pending and future requests.
+.It Cm destroy
+Destroy the given
+.Nm ggate
+provider.
+.It Cm list
+List
+.Nm ggate
+providers.
+.El
+.Pp
+Available options:
+.Bl -tag -width ".Fl s Cm ro | wo | rw"
+.It Fl f
+Forcibly destroy
+.Nm ggate
+provider (cancels all pending requests).
+.It Fl n
+Do not use
+.Dv TCP_NODELAY
+option on TCP sockets.
+.It Fl o Cm ro | wo | rw
+Specify permission to use when opening the file or device: read-only
+.Pq Cm ro ,
+write-only
+.Pq Cm wo ,
+or read-write
+.Pq Cm rw .
+Default is
+.Cm rw .
+.It Fl p Ar port
+Port to connect to on the remote host.
+Default is 3080.
+.It Fl q Ar queue_size
+Number of pending I/O requests that can be queued before they will
+start to be canceled.
+Default is 1024.
+.It Fl R Ar rcvbuf
+Size of receive buffer to use.
+Default is 131072 (128kB).
+.It Fl S Ar sndbuf
+Size of send buffer to use.
+Default is 131072 (128kB).
+.It Fl s Ar sectorsize
+Sector size for
+.Nm ggate
+provider.
+If not specified, it is taken from device, or set to 512 bytes for files.
+.It Fl t Ar timeout
+Number of seconds to wait before an I/O request will be canceled.
+0 means no timeout.
+Default is 0.
+.It Fl u Ar unit
+Unit number to use.
+.It Fl v
+Do not fork, run in foreground and print debug informations on standard
+output.
+.It Ar host
+Remote host to connect to.
+.It Ar path
+Path to a regular file or device.
+.El
+.Sh EXIT STATUS
+Exit status is 0 on success, or 1 if the command fails.
+To get details about the failure,
+.Nm
+should be called with the
+.Fl v
+option.
+.Sh EXAMPLES
+Make use of CD-ROM device from remote host.

+.Sh NAME
+.Nm ggated
+.Nd "GEOM Gate network daemon"
+.Sh SYNOPSIS
+.Nm
+.Op Fl h
+.Op Fl n
+.Op Fl v
+.Op Fl a Ar address
+.Op Fl p Ar port
+.Op Fl R Ar rcvbuf
+.Op Fl S Ar sndbuf
+.Op Ar "exports file"
+.Sh DESCRIPTION
+The
+.Nm
+utility is a network server for GEOM Gate class.
+It runs on a server machine to service GEOM Gate requests from workers
+placed on a client machine.
+Keep in mind, that connection between
+.Xr ggatec 8
+and
+.Nm
+is not encrypted.
+.Pp
+Available options:
+.Bl -tag -width ".Ar exports\ file"
+.It Fl a Ar address
+Specifies an IP address to bind to.
+.It Fl h
+Print available options.
+.It Fl n
+Do not use
+.Dv TCP_NODELAY
+option on TCP sockets.
+.It Fl p Ar port
+Port on which
+.Nm
+listens for connection.
+Default is 3080.
+.It Fl R Ar rcvbuf
+Size of receive buffer to use.
+Default is 131072 (128kB).
+.It Fl S Ar sndbuf
+Size of send buffer to use.
+Default is 131072 (128kB).
+.It Fl v
+Do not fork, run in foreground and print debug informations on standard
+output.
+.It Ar "exports file"
+An alternate location for the exports file.
+.El
+.Pp
+The format of an exports file is as follows:
+.Bd -literal -offset indent
+1.2.3.4 RO /dev/acd0
+1.2.3.0/24 RW /tmp/test.img
+hostname WO /tmp/image
+.Ed
+.Sh EXIT STATUS
+Exit status is 0 on success, or 1 if the command fails.
+To get details about the failure,
+.Nm
+should be called with the
+.Fl v
+option.
+.Sh EXAMPLES
+Export CD-ROM device and a file:
+.Bd -literal -offset indent
+# echo "1.2.3.0/24 RO /dev/acd0" > /etc/gg.exports
+# echo "client RW /image" >> /etc/gg.exports
+# ggated
