Compute the Ehrhart series encoded as a rational function for the
polytope given in ``fileName''. Writes the unsimplified rational function
to file ``fileName.rat''.
./ehrhart fileName
Compute the Ehrhart series encoded as a rational function for
the polytope given in ``fileName''. NEEDS Maple for
simplification of terms. Writes the simplified rational function to
file ``fileName.rat''.
./ehrhart simplify fileName
Compute the Taylor series expansion of Ehrhart generating
function up to degree
for the polytope given in ``fileName''.
