Terminology questions:

Is "Maxima" Identical to "DOE-Maxima" ?
Or is it a parallel branch of development?

Is the above-cited DOE-Maxima Reference Manual a replacement for 
the one at http://maxima.sourceforge.net/referencemanual/maxima_toc.html
(no author on document but attributed to William Schelter)?

Or is it a separate manual for DOE-Maxima?

Is the older manual maintained anymore? Should it be listed as "out of
date but useful"?

thanks
