We describe a general purpose Mathematica package for computing Superfield Operator Product Expansions in meromorphic N=2 superconformal field theory. Given the SOPEs for a set of ``basic" superfields, SOPEs of arbitrarily complicated composites can be computed automatically. Normal ordered products are always reduced to a standard form. It is possible to check the Jacobi identities, and to compute Poisson brackets (``classical SOPEs''). We present two explicit examples: a construction of the ``small'' N=4 superconformal algebra in terms of N=2 superfields, and a realisation of the N=2 superconformal algebra in terms of chiral and antichiral fermionic superfields.
