tigervnc-scraping-server 1.7.0-2ubuntu1 (s390x binary) in ubuntu zesty

 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 vncserver which uses screen scraping of an already
 running X server to provide its VNC desktop. The VNC desktop can be viewed
 by any vncviewer even on other operating systems.
 .
 Note: If you only want to scrap 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.
