Right now the above mentioned archive contains the population structure
and phylogeny trees part. Originally we started from writing two separate
programs, of which second one had the disequilibrium code. Now we are
in a process of merging them under one interface.

We plan to finish in the beginning of 1996, then the program will contain
disequilibrium analysis as well. In addition to the methods described in
the previous edition of Bruce Weir's book, it will have the multilocus exact
test implemented (the one described in D. Zaykin, L. Zhivotovsky & B.S. Weir,
1995. Exact test for association between alleles at arbitrary number of loci.
Genetica 96: 169-178).

Things move. The rest is a mess
