Description: Display informations on an external liquid crystal display
 Grab informations from the kernel and some subsystems and display it on an
 external liquid crystal display.
 .
 The use of special sequences (tokens) gives you full control of the layout,
 and therefore lcd4linux is completely independent from the display size.
