+#    - This is a generic wrapper script for starting any userspace VNC server
+#      to offer connectivity from the pvs contol console. The script expects
+#      start/stop in $1, the port to start on in $2 and the password in $3. The
+#      latter one should be changed to piping for security reasons ...
