I was telling the hack in post #4.
But for you I will translate my words into source code language (see attachment) so you will understand.

But in general I don't wanted to explain step by step what you need to do to get a deb.
It is faster to deliver one.

This is a quick hack, I think you could do it better. Remove the case and some other not needed functions. However I think it does not hurt but it is ugly.
