Viper Window Manager (VWM) is a lightweight, extensible window manager for
the console. Originally, VWM was designed to be the reference implementation
of libviper. In fact, the two projects were initially one before public
release.

From conception, VWM was designed to be both lightweight and ssh
friendly. Character based line-art compresses very well as do the escape
sequences which handle cursor manipulation. This makes VWM quite suitable
for low-bandwidth, remote connectivity over ssh.

It is also very easy to extend the functionality of VWM. By following a
few simple API rules, anyone can create a "native application" which will
appear on the VWM Main Menu. The mechanism for this is very similar to
Mozilla-style plugins.

See /usr/doc/vwm-2.0.2/samples/vwmrc for information on customising VWM.
