I fixed that now in the trunk (r64016); the old version is still around
for compatibility reasons. Please use the new name.

You can also use write_graphviz_dp() to do your printing; that will allow
you to just fill in a dynamic_properties() object with whatever external
property maps you want. There is also a function_property_map that's not
in BGL but you can find by searching the Boost mailing lists; you can use
that to create your vertex names, or you can just create a
shared_array_property_map that you fill in manually with the names.

I also added warnings in graph_concepts.html and graph_traits.html about
subclassing BGL graphs. Please see if you like the wording or if you
think there are any other places those warnings need to be.
