  I outline the power counting scheme recently introduced by M. Savage, M. Wise
and myself for the effective field theory treatment of nucleon-nucleon
scattering. It is particularly useful for describing systems with a large
scattering length, and differs from Weinberg's power counting. A
renormalization group analysis plays a big role in determining the order of a
given operator. Pions are ignored in this discussion; how to incorporate them
is discussed in M. Savage's talk, nucl-th/9804034.
