SVN Repositories allow you to store and access versioned files via the popular Subversion version control system.
After a SVN Repository has been created on the system the repository will be at Version 0 awaiting you first commit. You will be told the checkout URLs for the repository. There will be an http url and and https url for secure access. You will need to set up an HTTP client in order to use this checkout URL.
New SVN Revisions are created automatially everytime a user commits a revision to the repository.
