Maxima: textbook



Hello

is there any book about Maxima? I have the Maxima manual (which is too
long) and Minimal Maxima by Robert Dodier (which is very nice and explains
many things which are not clear from the voluminious manual, but it is too
short).

I have visited Docs part on maxima homepage. Is there any printed textbook
about Maxima (in English or German)?

Thanks.
Robert
