This my fork of PSMTabBarControl. It was originally created by http://www.positivespinmedia.com/dev/PSMTabBarControl.html, then updated at http://code.google.com/p/maccode/source/browse/#svn/trunk/Utilities/PSMTabBarControl. The initial commit of my fork is from r291 of the Google code repo. Project hasn't been updated on either site in a few years, but still works well. My fork is an attempt to modernize some of the code and interface for my own purposes, but I can't promise I'll keep maintaining it.
