title: SVN+SSH, not having to do ssh-add every time? (Mac OS)
body: <p>I know the answer is out there, but I'm pretty Unix-dumb and probably wouldn't recognize the solution if it hit me in the face.</p>
  
  <p>I'm on a Mac, connecting to a SVN server via SSH tunneling.  I have to <code>ssh-add privateKey.txt</code> every time I want to connect to the SVN server (Both Cornerstone and Xcode are connecting to SVN).  </p>
  
  <p>Is there a way to "save" the key somewhere so I don't have to do this every time?  Add it to my Keychain? Some config file? Start up script? </p>
