I recently got an email from a BarCamp friend, Mark Sailes, telling me about his new site http://www.svn-checkout.co.uk. I am a big fan of subversion and always looking for more tips and tricks for using it better so I popped over to have a look. Its a nice site with some very useful short articles on various subjects related to subverison. In particular the article on releasing new versions of sites caught my eye. Mark suggests use of a checked out version of code rather than an exported one, and using the switch command to upgrade to the next tagged version as needed. He completes the setup with an apache configuration trick to avoid any of the subversion information being served to the outside world. I've usually just exported new versions as needed but this trick is a definite alternative and the article itself guides the reader through each step of the way. Nice one Mark :)
