  OFFICE MEMO          A definite Integral                    Date:3/16/92
Consider the definite integral of: x^3/(Exp[x]-1) from 0 to infinity. The value
is knownto be Pi^4/15. When trying to evaluate this integral in Mathematica,
the application quits for no  apparent reason. Macsyma gives the result:
-Pi^4/15 plus terms involving Polylogarithms (with an unevaluated limit). I
can't get Macsyma to "evaluate" the indicated limit.
