A general-purpose Mathematica package for compuing operator product expansions of composite operators in meromorphic conformal field theory is described. Given the OPEs for a set of "basic" fields, OPEs of arbitrarily complicated composites can be computer automatically. Normal ordered products are always reduced to a standard form. Two explicit examples are presented: the conformal anomaly for superstrings and a free field realization for the B-hat_2 Kac-Moody algebra.
