In order to use fvwm95 as your window manager, you must change your
.xinitrc or .xsession appropriately and add a line similar to the
following:

	exec ${PREFIX}/bin/fvwm95

Icons have been installed into ${PREFIX}/icons, and a system wide 
configuration has been put in ${PREFIX}/lib/X11/fvwm95/system.fvwm95rc. To 
use your own configuration, copy ${PREFIX}/lib/X11/fvwm95/system.fvwm95rc to
~/.fvwm95rc and edit as appropriate.
