Unlike other windowing systems, X does not impose a particular `look and feel' on the user; rather, the user may select one of a number of `window managers' that provide different user interfaces for common operations such as moving and resizing windows. Window managers are X client applications that have a special status allowing them to manipulate the windows of other X clients. Any window manager that conforms to the ICCCM (a standard published by the X Consortium) may be used with WAVE; among these are fvwm, olwm, and olvwm, included in source form with most Linux distributions and widely available elsewhere (olwm is also standard on Sun workstations); and mwm (the Motif window manager, included with most current commercial UNIX systems). The Open Look window managers (olwm and olvwm) are particularly recommended, since the others do not support certain Open Look features of WAVE (notably spot help and `pinnable' popups). If you are using an MS-DOS PC or an X terminal to access WAVE, the window manager must usually be run remotely, often on the same computer that runs WAVE.
