sortedsums is a collection of tools for enumerating small solutions to
certain types of Diophantine equations. See BLURB for a more detailed
advertisement.

To compile the programs:

   % make

To test:

   % ./cubepppp 1 999 | ./dist

After a few seconds you will see the following table:

The last line says that on the Fermat surface away from the exceptional
lines there are 35208 rational points of height at most 997. The ratio
35208/997 is approximately 35.313942.
