[Q] any software to compute Nei and Li coefficient?

[JAMES O. MCINERNEY]

Hi,

Does anyone know of any software that calculates Nei and Li's coefficient
for studying genetic variation in terms of restricition endonucleases:

PNAS 76, 10, 5269-5273 (1979). Mathematical model for studying genetic variation in terms of restriction endonucleases.

Freeware or public domain software is preferrable (otherwise I could be using
a pencil and paper :-o  ).

TIA,

James
