Program items:

the "work" routine needs to be fixed still.  It currently uses relations from Jaeger and Cooke, but these give 
spurious negative results.  This fix should be in place by the end of November, 2004; if not, let me 
(mellis@memphis.edu) know, please.  

Please let either of us know if you find bugs or if you make interesting and significant additions to the code.

Many thanks,

ME and JG
