 pip supports the URL schemes ``svn``, ``svn+svn``, ``svn+http``, ``svn+https``, ``svn+ssh``.
 
+Here are some of the supported forms::

+    [-e] svn+https://svn.example.com/MyProject#egg=MyProject
+    [-e] svn+ssh://svn.example.com/MyProject#egg=MyProject
+    [-e] svn+ssh://[email protected]/MyProject#egg=MyProject
