I'll try to do so later.

I think the parser is written but the semantic actions are not, so it
isn't functional yet. We're trying to unify on some kind of system for
dynamic properties, so that we can deal with reading in arbitrary
vertex/node attributes. I have a GraphML parser that handles dynamic
properties, which hopefully will also work well in the new GraphViz
parser. If I get some time post-1.32.0 (hah!), we'll try to get all
those bits in.

We promised to keep the parts of the BGL needed for the Python lib in
working order. But I've marked borland and vc6 unusable because they've
never really been usable and are a huge maintenance burden.
