For any users currently using the devel subversion repository.  If you need
to update, please send me an e-mail to get information on how to switch over
to our new server.

Thanks,
Carson

Hi!

I've tried again from two different machines, and I can't do a "svn co" nor
"svn update" on the malachite server. Can you verify the server and the svn
service is OK on your side?

Many thanks / Ramón.
