 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 package provides a VNC client for X. With this you can connect to a
 VNC server and display its content. There are VNC servers available for other
 operating systems.
