This discussion has also moved me towards some generalization of CONSENSE
in the 4.0 release of PHYLIP (not due soon, alas).  But what puzzles me is
what features people need.  I guess we need to be able to read in a file
of trees and make a variety of kinds of consensus trees among them.
But as for tree distances, how would users want the input trees to be fed
in?  In pairs in the same file?  In two files, whose corresponding members
get compared?  In two files, one with one tree and another with many,
each of which is to be compared to the one tree?

I guess the answer is "all of the above, as options".  If anyone has
a feeling as to which is the "natural" method input of trees to such a
consensus-and-tree-distance tool, do let us know.
