The SVN snapshot  can be updated with SF shell access using SSH. There is a script called update-svn-snapshot.sh that can do all the required steps (checking out SVN, packing the source tree into one archive, updating the website link). See previous section how to create a shell.
cd /home/project-web/bochs/sitebin/ ./update-svn-snapshot.sh
The SVN snapshot link can be found on the bottom of the page getcurrent.html.
