    (description "TigerVNC implements a @acronym{VNC, Virtual Network Computing}
client and server.  @dfn{VNC} is a remote display system that lets you view and
interact with a virtual desktop environment running on another computer on the
network.  Client and server may be running on different operating systems and
architectures.

TigerVNC uses a variant of Tight encoding that is greatly accelerated by the use
of the libjpeg-turbo JPEG codec and performs fast enough to run even 3D or video
applications.  It also provides extensions for advanced authentication methods
and @acronym{TLS, Transport-Level Security} encryption.

This package installs only the VNC client (@command{vncviewer}), the application
used to connect to VNC servers such as the tigervnc-server package.")

    (description "TigerVNC implements a @acronym{VNC, Virtual Network Computing}
client and server.  @dfn{VNC} is a remote display system that lets you view and
interact with a virtual desktop environment running on another computer on the
network.  Client and server may be running on different operating systems and
architectures.

TigerVNC uses a variant of Tight encoding that is greatly accelerated by the use
of the libjpeg-turbo JPEG codec and performs fast enough to run even 3D or video
applications.  It also provides extensions for advanced authentication methods
and @acronym{TLS, Transport-Level Security} encryption.

This package installs the VNC server.  Permitted users can log into a graphical
session on the machine where the server is running, using a VNC client such as
the tigervnc-client package.")))
