Hi there,
I've updated the website to reflect the states of things a little
better:
- graph-tool is now a python module, instead of a stand-alone
program.
- The old stand-alone version of graph-tool is considered
deprecated. It differs too much from the current version, and
will no longer be maintained.
- There is not yet an official release of the library. It must be
obtained directly from git. I'll do a release once the
documentation is 100% done.
- The new documentation is online and ~80% complete.
The plan is to finish this up as fast as possible, and proceed to
include new algorithms (such as flow, new generators, k-core, etc).
Hopefully, things will flow more smoothly from now on.
Testers are welcome. 
Best regards,
Tiago
