read-only git mirror of an svn repository

What would be the best way to set up a read-only git mirror of an existing svn repository, and set up post-commit hooks such that whenever someone commits to svn, the git mirror is automatically updated? Mainly, I'd like to run git-svn clone just once, on the server, and then let people just check out from git without having to git-svn clone the entire svn repository themselves.
