Okay,
I've put together a very preliminary integral testing set
(only 25 right now). It compares the Sage integration
(via Maxima) to results from Schaum's. It also does timing
comparisons of Maxima and FriCAS (Axiom).

Ok, I consider this vote closed and since there were only "+1" votes
also a positive conclusion has been reached.

Well, you have been happy running clisp, even though it is

ECL is presumably faster than clisp, but that is not even remotely

Should the SR parser support equations?

Yes, it should. In fact, the parser itself supports, lists, tuples,

You just run "hg ci" to commit the merge. Then to make the changes
active, you have to start sage with "sage -br".

Oh yeah: Another thing I haven't done in ages is to get the info from
the contributors list and have them added to the Dev Map. This should
also be a ticket for each release in case we have somebody new
contributing.
