I assume Gail's code can be found, as can Gail, who last I knew
lived in the Boston/Cambridge Massachusetts area and worked for
a software company writing for Macintosh computers.
On the other hand, if you wish to write a new GB package based
on the best alternative today, I think you could do so. Another
possibility is to write an interface program that takes a macsyma
problem statement and transfers the notation to some one of
the other programs (and back). I think that Bill Schelter's
xmaxima interfaced with one of the systems you mention.
