-program connects to an instance of
-.Xr pounce 1
-at
-.Ar host
-and runs
-.Ar command
-for each private message
-or message containing the user's nickname

-through the environment.
-.
-.Pp
-The arguments are as follows:
-.Bl -tag -width Ds
-.It Fl c Ar cert
-Load the TLS client certificate from
-.Ar cert .
-If the private key is in a separate file,
-it is loaded with
-.Fl k .
-.It Fl k Ar priv
-Load the TLS client private key from
-.Ar priv .
-.It Fl p Ar port
-Connect to
-.Ar port .
-The default port is 6697.
-.It Fl t Ar path
-Trust the self-signed certificate loaded
-from
-.Ar path
-and disable server name verification.
-.It Fl u Ar user
-Set the username to
-.Ar user .
-The default username is
-.Dq pounce-notify .
-.It Fl w Ar pass
-Log in with the server password
-.Ar pass .
-.El
-.
-.Sh ENVIRONMENT
-The following variables
-are set in the environment of
-.Ar command :
-.Pp
-.Bl -tag -width "NOTIFY_MESSAGE" -compact
-.It Ev NOTIFY_CHANNEL
-The name of the channel
-in which the message was sent.
-Unset if the message was private.
-.It Ev NOTIFY_HOST
-The hostname of the user who sent the message.
-.It Ev NOTIFY_MESSAGE
-The content of the message.
-.It Ev NOTIFY_NICK
-The nickname of the user who sent the message.
-.It Ev NOTIFY_TIME
-The time the message was sent,
-in
-.Sy server-time
-format.
-.It Ev NOTIFY_USER
-The username of the user who sent the message.
-.It Ev POUNCE_HOST
-The host
-.Nm
-is connected to.
-.It Ev POUNCE_PORT
