VNC stands for Virtual Network Computing. It is, in essence, a remote display
 system that 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. For this purpose, it implements a
 client/server model.
 .
 This package provides a VNC server that perform screen scraping of an already
 running X server to provide its VNC desktop. The VNC desktop can be viewed
 by any VNC viewer even on other operating systems.
 .
 Note: If you only want to scrape your local X11 server, you should consider
 the tigervnc-xorg-extension package. This package provides the vnc extension
 for your local X11 server. The usage of this extension is more efficient
 than a scraping vnc server.
