Subversion

• Subversion uses a client-server model, requests
  are made by the client and the server processes
  those requests.
• SVN-Commit a commit operation uploads your
  changed files back to the subversion server
• SVN-Update latest files are pulled from server
• SVN-Resolved files are merged during update

  documents section on hanley.co.nr
