Make sure you are on your master branch:
cd /path/to/project/root
git checkout master

Update your own version. Try to do it at a time when no one else will be committing. (You can check that you don't have any committed but not pushed changes with gitk &.)

./scripts/fetch_rebase
[This script combines the commands git-svn fetch and git-svn rebase for convenience.]

The manual: http://svnbook.red-bean.com/en/1.2/svn.advanced.locking.html

The useful info: http://marc.info/?l=subversion-users&m=117814302607694&w=2

cd /repos/path/of/interest
find . -type f -exec svn lock '{}' ';'

Checkout into a new directory:

svn checkout -r 1310 http://svn.repositoryurl.example.com/path/to/repos newlocalfolder
# Checks out a new working copy at r1310

Or update a working copy to a given revision number:

cd local-folder-for-repo
svn update -r 1310
# Updates an existing working copy to r1310

(Note: You cannot make changes and commit from an old checkout like these.)
