Automatic file update on a non-svn folder while doing svn commit

I have svn repository and virtual hosts set up on same linux server. Whenever the developers commit the changes, I want the site fi开发者_JAVA百科les(files at webroot) too get updated at the same time. The files at webroot is not a svn working copy. I was able to update another svn working copy using post commit hook, but dont know how to update another non-svn folder.

You can perform an svn export from a post-commit hook.
