     Some notes about using SSH with Mercurial:
-    - SSH requires an accessible shell account on the destination
-      machine and a copy of hg in the remote path or specified with as
-      remotecmd.
-    - path is relative to the remote user's home directory by default.
-      Use an extra slash at the start of a path to specify an absolute path:
