That's a point.  I wonder if it was an official project?

Sounds like a plan.  Anybody know anyone in AMS to contact about the

Thanks!  Hopefully I'm on the right track.  I think once I've gotten
the rest of the dimensional analysis algorithm written up I might be
able to start looking at actual code along with the text.  Reviewing
the other packages out there is probably going to be a bit of an
ongoing thing, although I will try and write a piece about the Maple
package RSN.  And I also want to give the sistyle package a try - if
that's as useful as I'm hoping it is I would like to expand Axiom's tex
abilities to output sistyle formatting for units.  

Heh - actually, that raises another point.  How should packages deal
with subject specific LaTeX?  Say, for example, that I want to use a
chemical formula style file for a chemical equations package, just like
I want to use sistyle for units.  How do I teach Axiom's TeX routines
new tricks?  Domain specific tex output?
