Right. it *used* to be there :-(

The problem is, that due to the new layout (based on the evaluator), the 
corresponding layer in lcd4linux where liblcd4linux and the python 
bindings based upon is no longer present.

As we were facing lots of problems with libtool, too, I decided to 
deactivate liblcd4linux temporarily.

The new internal layout of lcd4linux uses very basic hardware display 
access functions; all of the special functions that various displays 
provide (GPIO's, contrast & backlight, fan reporting, ...) are 
implemented as 'plugins' to the evaluator. The display-specific stuff 
(drawing text, ...) itself is implemented as 'widgets'. Some displays 
need a regularly called timer function, too, which is implemented as a 
'timer' in lcd4linux, which is triggered by the lcd4linux main loop.

At the moment I have absolutely no idea where to find a common layer 
which liblcd4linux could provide to other applications. Yourt input and 
ideas are welcome!


bye, Michael
