-listed on the command line.
-Changes do not take effect until
-.Xr pounce 1
-is restarted.
-Configuration files
-are searched for
-in the same manner as
-.Xr pounce 1 .
-.
-.Pp
-The options are as follows:
-.Bl -tag -width Ds
-.It Fl a
-Allow setting all options,
-including those that
-may render
-.Xr pounce 1
-inoperable.
-.
-.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 h Ar host
-Connect to
-.Ar host .
-The default is the value of
-.Cm local-host
-from the configuration files.
-.
-.It Fl p Ar port
-Connect to
-.Ar port .
-The default is the value of
-.Cm local-port
-from the configuration files,
-or 6697.
-.
-.It Fl t Ar trust
-Trust the self-signed certificate loaded from
-.Ar path
-and disable server name verification.
-.
-.It Fl u Ar user
-Set the username to

-.Sh DESCRIPTION
-The
-.Nm
-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
-while the user is marked as away.
-The nickname is matched case-sensitively
-and must be surrounded by whitespace or punctuation.
-Information about the message
-is passed to the command
-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
