+.Sh NAME
+.Nm ngctl
+.Nd netgraph control utility
+.Sh SYNOPSIS
+.Nm
+.Op Fl d
+.Op Fl f Ar filename
+.Op Fl n Ar nodename
+.Op Ar command ...
+.Sh DESCRIPTION
+The
+.Nm
+utility creates a new netgraph node of type
+.Em socket
+which can be used to issue netgraph commands.
+If no
+.Fl f
+flag is given, no
+command is supplied on the command line, and standard input is a tty,
+.Nm
+will enter interactive mode.
+Otherwise
+.Nm
+will execute the supplied command(s) and exit immediately.
+.Pp
+Nodes can be created, removed, joined together, etc.
+.Tn ASCII
+formatted control messages can be sent to any node if that node
+supports binary/ASCII control message conversion.
+.Pp
+In interactive mode,
+.Nm
+will display any control messages and data packets received by the socket node.
+In the case of control messages, the message arguments are displayed in
+.Tn ASCII
+form if the originating node supports conversion.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl f Ar nodeinfo
+Read commands from the named file.
+A single dash represents the standard input.
+Blank lines and lines starting with a
+.Dq #
+are ignored.
+.It Fl n Ar nodename
+Assign
+.Em nodename
+to the newly created netgraph node.
+The default name is
+.Em ngctlXXX
+where XXX is the process ID number.
+.It Fl d
+Increase the debugging verbosity level.
+.El
+.Sh COMMANDS
+The currently supported commands in
+.Nm
+are:
+.Pp
+.Bd -literal -offset indent -compact
+config get or set configuration of node at <path>
+connect Connects hook <peerhook> of the node at <relpath> to <hook>
+debug Get/set debugging verbosity level
+dot Produce a GraphViz (.dot) of the entire netgraph.
+help Show command summary or get more help on a specific command
+list Show information about all nodes
+mkpeer Create and connect a new node to the node at "path"
+msg Send a netgraph control message to the node at "path"
+name Assign name <name> to the node at <path>
+read Read and execute commands from a file
+rmhook Disconnect hook "hook" of the node at "path"
+show Show information about the node at <path>
+shutdown Shutdown the node at <path>
+status Get human readable status information from the node at <path>
+types Show information about all installed node types
+write Send a data packet down the hook named by "hook".
+quit Exit program
+.Ed
+.Pp
+Some commands have aliases, e.g.,
+.Dq ls
+is the same as
+.Dq list .
+The
+.Dq help
+command displays the available
+commands, their usage and aliases, and a brief description.
+.Sh EXIT STATUS
+.Ex -std
+.Sh SEE ALSO
+.Xr netgraph 3 ,
+.Xr netgraph 4 ,
+.Xr nghook 8
+.Sh HISTORY
+The
+.Nm netgraph
+system was designed and first implemented at Whistle Communications, Inc.\& in
+a version of
+.Fx 2.2
+customized for the Whistle InterJet.
