How can I downgrade the version of an SVN working copy?
http://subversion.tigris.org/faq.html#working-copy-format-change
Having the issue where I try to update in svn and it gives me "This client is too old to work with working copy"
They've provided a .py script that is supposed to skip the unknown format. How do I use this python script so that I can go back to using svn as normal from windows command line?
