There has been several attempts at this in the past few months.  Is there a
central location to link them together?

On a related approach, is there any attempt to use Swig to wrap around GiNaC
(http://www.ginac.de/)?  It is claimed to be a no-frills C++ engine written
specifically for higher level languages to adopt.

I think an eventually practical symbolic package has to be written in C/C++
for performance's sake. These pure Python attempts would be very useful for
interface designs.
