tightvnc-java binary package in Ubuntu Lunar s390x

 VNC stands for Virtual Network Computing. It is, in essence, a remote
 display system which allows you to view a computing `desktop' environment
 not only on the machine where it is running, but from anywhere on the
 Internet and from a wide variety of machine architectures.
 .
 This is the vnc java applet file that the tightvncserver can distribute
 to the client. In addition a command line program that starts the java based
 vnc viewer locally is included.
