openABK support for programmable displays and gateways

To our deepest regret, we have not translated this document into English yet.
After a 'good start', the demand for OpenABK seems to be low now,
so we (MKT Systemtechnik) will not put a lot of effort to document it
        - unless someone asks for it.
If you plan to use OpenABK, please contact the author.

So for a start, please use the latest German version of this file,
and -if really necessary- use this automatic translator even though the result may be funny.
