Greetings GRASS World !!!

I am looking for suggestions to solving an application problem.
Given a watershed with three points in it (three lines in a file
in the site_lists directory), I want to be able to add n more points,
and for each one of those points, have GRASS tell me which one of
the three original points it is closest to.  Either respond to
grassu-list and I will read it or give me a call.  Thanks in advance.
