Hi Eric,

I've gone through your ob-maxima.el, and tried to re-work it to the
point where it can be included into Org-mode -- mainly just switching to
a couple of Babel "best practices", and replacing some shell script
munging with elisp munging.

Please try out the attached version (packaged as a patch against the
current Org-mode head) and let me know if it works --- i.e., If I
haven't broken it too badly.  If it works I think we can fold it into
Org-mode immediately.

Cheers -- Eric
