Maxima and Macaulay2/Singular



Hi list,

I am not really satisfied with algsys for solving/simplifying polynomial 
equations.
I have a set of polynomial equations (40 variables, 70 equations, degree 4).
I canceled Maxima after 10 hours of computation.
This was on a recent machine, with 16 Gb given for the heap to sbcl.
Then I extracted the polynomial set of equations, put it in a script for 
Macaulay2,
and the dim command of Macaulay told me, within some seconds, that there 
were no solutions.

Question:
Does somebody know, if there is some functionality available,
for calling Macaulay or e.g. Singular within Maxima?

Regards
Andre
