SVN certainly has its problems but there are some really nice clients available for OS X (e.g., Cornerstone <a href="http://www.zennaware.com/)">http://www.zennaware.com/)</a>. It works even without a SVN server. You can just make a local repository and still get all the benefit from version control. Of course, you could do most of this with command line SVN built into OS X but some of these systems have nice interactive features. For instance, if I change a file in CCL and command tab to Cornerstone it already shows the the modified files and even a side by side diff. In that sense CCL and version control already feel very connected.</div><div><br></div><div>With version control there is not a huge need for backup files. I do agree, however, it would be nice to have that separate folder collecting backups. Perhaps these backup files would automatically be deleted after n days.</div><div><br></div><div>Alex</div><div><br></div><div><br></div><br><div><div>On Aug 5, 2009, at 2:50 PM, Ron Garret wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>I wanted to change the way Hemlock stores backups.
