Re: 64bit compatibility

Fabrice

I've been running for several months on a 64-bit linux configuration
without a problem. I'm using Fedora Core 7 and Python 2.5 on this, but
I believe others have used Suse (not sure whether on 64-bit or not)
without problems. But your point about handling multiple python
installs on the same machine is a good one.

I suggest retrieving the most recent code from Subversion, rather than
using the Nov 2006 release. It is available from
https://trondheim.cs.washington.edu/svn/opus/. We no longer install
opus/urbansim into site-packages, but rather into a user-specified
workspace.
