I tried `make htmldocs`. I would say it's more like Doxygen/Javadoc
documentation than a book. Fore the record - I didn't manage to build
PDF on Ubuntu Linux.

Wow, thanks a lot for this link! Fortunately I have some basic
knowledge of German language. I think I could read this book with a
dictionary. BTW in my opinion German is a pretty simple language
(comparing to English for instance) so it should not be a real problem
to anyone to learn its basics in a month or two.
