ROLF is made up of four major components.

1. The Wimp server
   A standalone program that mediates access to the screen and handles input from the user (keyboard and pointer).
2. The Libraries
   • The Image Library
   • The Rolf App Library
3. The ROLF Essential Applications
   • Iconbar (provides the icon bar and backdrop)
   • Filer (provides the filer interface)
   • The Task Manager (Tux)
4. The ROLF Utility Applications
   • Viewer (An image viewer)
   • MPlayer (Audio/Video player based on MPlayer)
   • Terminal (A simple terminal program)

Applications are expected to have as small a footprint as possible and to avoid any display optimisation techniques (e.g. caching decompressed JPEG images) in order that they may run on low powered machines.
