Here are the command line options that Geomview allows:
-c "(ui-panel main off)"
Since command includes parentheses, which have special meaning to
the shell, command must be quoted.  Multiple -c options are allowed.
     
Listening to command streams on TCP ports can be a security risk, as Geomview itself does not take any security precautions, it simply executes all commands fed to it through the network socket. This also implies that disk-io can be initiated remotely.
Examples:
-M objectnamegeomstuff or togeomview.  This actually listens to the
named pipe /tmp/geomview/objectname; you can achieve the same
effect with the shell commands:
                         mkdir /tmp/geomview
               mknod /tmp/geomview/objectname p
          (assuming the directory and named pipe don't already exist), then executing the GCL command:
(geometry objectname < /tmp/geomview/objectname)
(see (geometry ...))
          
-Mc pipename-Mcs fred-Mcsin 40000ui-panel command. See (ui-panel ...).
