Ctwm is a window manager for the X Window System. It provides
titlebars, shaped windows, virtual screens (workspaces), several forms
of icon management, user-defined macro functions, click-to-type and
pointer-driven keyboard focus, and user-specified key and pointer
button bindings. It is actually twm (Tab Window Manager) from the MIT
X11 distribution slightly modified to accommodate the use of several
virtual screens (workspaces). It is heavily inspired from the
Hewlett-Packard vuewm window manager. In addition, ctwm can use
coloured, shaped icons and background root pixmaps in XPM and JPG format,
as well as any format understood by the imconv package [from the
San Diego Supercomputer Center] and xwd files. Ctwm can be compiled
to use both, either or none of the above icon/pixmap formats.
