No -- I wasn't aware of it.
As a newbie, I'll ask now -- what is the best way to suss out what
functions/packages are available? (such as impdiff). Being a heavy user
of *TeX, and R, I'm used to the concept of lots of 'add-ons', and while
I have loads of experience tracking down which package does what for
*TeX and R, as a Maxima newbie, am happy to be told the best way to find
this or that on my own (minimizing the number of simplistic questions
posted to the maillist)..
Thanks again...
