.Sh DESCRIPTION
.Nm
prints information about CADET tunnels and peers.
It can also be used for command-line based CADET tunnels using the
.Fl o Ar SHARED_SECRET
option to open a port on a receiving
.Ar PEER_ID
and using
.Nm
.Ao Ar PEER_ID Ac
.Ao Ar SHARED_SECRET Ac
to establish one circuit to that peer from any other peer.
The receiving process will only accept one incoming circuit, but several commands using the same
.Fl o
can be issued to satisfy multiple requests.
For one-to-many communication
.Xr gnunet-social 1
may be better suited, however.
