I'm new to using the Boost Graph library and am bewildered by its
(seemingly essential) complexity. A solution to the simplistic problem
I pose below would help provide a workable context around which to
wrap my brain and would be most appreciated.

My apologies if a similar question has been asked before. A search
through the mailing list archive did not return promising results.
Also, I have, incidentally, ordered The Boost Graph Library text and
am very much looking forward to its arrival.
