I see now in the reference manual that the definition
of VERB uses INTEGRATE as an example.

I would *never* have thought in a million years to
look there for the answer to my question.

Someone who knows Maxima *needs* to go through the
reference manual and put some kind of indication on
each function, telling new users whether that function
is a noun or verb by default.

And again, a tutorial ought to be fairly VERBose in
explaining the difference.

Thanks again,
Dan
