fbcompose - A compositing addon for fluxbox window manager.

 fbcompose(1) is an optional compositing addon for fluxbox window manager. It
 augments fluxbox with a number of graphical features. Most notably, fbcompose
 allows fluxbox to properly display applications that require compositing
 (docky, for example), adds support for true window transparency (as opposed to
 fluxbox's pseudo transparency) and provides a plugin framework to extend the
 compositor's functionality.

 As this is still a beta version of the compositor, the bugs are likely.
