 Number of interactive authentication attempts in case authentication with the server fails (wrong password?). A value that equals 0
 disables interactive authentication completely and requires that a private SSH key has been given on the command line or in the
 session profile or that the \-\-password command line option is used.

+.SH BROKER OPTIONS
+In case you want to retrieve \fBx2goclient\fR session profiles from an X2Go Session Broker use the following options:
+.TP
+\*(T<\fB\-\-broker-url=<URL>\fR\*(T>
+Specify the <URL> of the X2Go Session Broker. X2Go Client can access http:// and ssh:// style URLs.
+
+Syntax of <URL> for HTTP brokerage:
+
+http(s)://<user>:<password>@<hostname>:<port>/path/to/broker

+Syntax of <URL> for  SSH brokerage:

+ssh://<user>:<password>@<hostname>:<port>/usr/bin/x2gobroker (or any executable that
+provides the broker via SSH).

+.TP
+\*(T<\fB\-\-broker-cacertfile=</path/to/cafile.crt>\fR\*(T>
+Specify a special (self-signed) root-CACert file that shall get used when connecting to an X2Go Session Broker via https (SSL). (Not implemented, yet).
+.TP
+\*(T<\fB\-\-broker-noauth\fR\*(T>
+The X2Go Session Broker is accessible without authentication. (Not implemented, yet).
+.TP
+\*(T<\fB\-\-auth-id=<USERNAME>\fR\*(T>
+Use this <USERNAME> for authenticating against the X2Go Session Broker. This option mostly makes sense together
+with \fI--broker-autologin\fR or \fI--broker-ssh-key\fR.  (Not implemented, yet).
+.TP
+\*(T<\fB\-\-broker-autologin\fR\*(T>
+For SSH based X2Go Session Brokers. If an SSH agent is available or default key files exist then
