Python svn bindings for Subversion?

[Mike B]

I'm trying to get Subversion 'hook scripts' working on an Ubuntu box and the
following fails.

from svn import fs, repos, core, delta

As far as I can tell there are two Python Subversion libraries, 'pysvn' and
'svn':
'pysvn' from http://pysvn.tigris.org/ appears to be a client side interface and
isn't what I need.
'svn' appears to be a SWIG wrapper and could be what I'm looking for, but I
cannot find it anywhere.

Can anyone point me in the right direction.

Thanks

Mike
