title: What's the best way to clean up a Subversion repository?
body: <p>I have a growing repository containing a dozen or so projects that I maintain using TortoiseSVN (as I am completely new to this and don't know the ins and outs yet). The space I have to hold the repository is limited so I want to back it up, then remove some of the older versions. For example, if a project is at version 50, I want to keep only 50,49,48.</p>
