Re: [GNUnet-developers] gnunet-python library

[Christian Grothoff]

Dear Andrew,

First of all, great progress, this looks like the DBus stuff is
starting to be really useful!

As with DBus, I'd be happy to setup a directory svn/gnunet-python/ on
gnunet.org for you, so that the code is also available from the
'central' code repository.

Also, it would probably be helpful to extend the developer handbook
with a chapter on the Python binding (and DBus...).  At the least, we
clearly should mention in the handbook that the binding(s) exist(s).

I don't recall if you have the permissions set up for that; if you don't
let me know and I'll be happy to fix them.

Happy hacking!

Christian
