Well, this doesn't mean it's v3, no? It's the license text of version 2, I
think.

It even supports "wholes", so I think it's even better.

Maybe worth to discuss this in a new thread, but having Jay and Kishore
working on new algorithms, it might be time to think about a function
"cleanup" and version pgRouting 2.0. Don't you agree?

It doesn't need to be all new, but function names and wrappers could be
reorganized, pgRouting could be checked for compatibility with PostGIS 2.0
and Steve's idea to provide functions that return the "raw data" is also a
good idea.
