I guess all of this is in the CVS, of course... I wondered also if 
there was a way to download all of the boost documentation (HTML 
format) for offline browsing, rather than going to the web site every 
time (maybe this is intentionalk though). I mean, a way different than 
downloading the CVS documentation.

I have yet a new question: is it possible to have, as a bundled 
property, references to objects and not just the object themselves ?

IE,

        typedef adjacency_list<mapS, vecS, undirectedS, myClass > Graph;

works, but I can't manage to have:

        typedef adjacency_list<mapS, vecS, undirectedS, myClass &> Graph;

(A pointer, though, is ok as I have noted on one of my earlier mails).

I have noted, though, that function such as 
add_vertex(const VertexProperties& p, adjacency_list& g) do take a 
reference to a VertexProperties. So should I assume that if I construct 
my graph in this way (via use of add_vertex, etc...) my bundled 
properties will just be references, ie, no copy construction will occur 
( and after running my graph algorithms, the modifications on the 
bundled properties will still be accessible)?
