Binary search through svn revisions This tool's purpose is to help you determine which revision of a subversion repository contains a change. It does this by employing a binary search. It will manage the current revision of your checkout directory, and narrow in on the target revision, as you give it clues about the current revision such as "before" (this revision is before the one you want) or "after" (this revision is after the one you want).
