Maple V comes with both Linux and Win32 (and Mac) binaries; Linux and
Win32 have both GUI and console interfaces.  I suppose I could do some
experimenting...  ;)  Anyone have any particularly hard math problem for
me to crunch?

   For the Japanese, by contrast, the human child is
   born in a state of loneliness, incapable of communication
   with the rest of humanity.  The way out of this
   loneliness leads by way of tenderness into a proper
   sense of dependence on others.
