     The location of the source is added to the new repository's

     For efficiency, hardlinks are used for cloning whenever the source
     and destination are on the same filesystem (note this applies only
     to the repository data, not to the checked out files).  Some
     filesystems, such as AFS, implement hardlinking incorrectly, but

     atomic (making sure REPO is not modified during the operation is
     up to you) and you have to make sure your editor breaks hardlinks
     (Emacs and most Linux Kernel tools do so).
 
     If you use the -r option to clone up to a specific revision, no
     subsequent revisions will be present in the cloned repository.
     This option implies --pull, even on local repositories.
 
     See pull for valid source format details.
 
     It is possible to specify an ssh:// URL as the destination, but no

     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:
         ssh://example.com//tmp/repository
     - Mercurial doesn't use its own compression via SSH; the right thing
       to do is to configure it in your ~/.ssh/config, e.g.:
         Host *.mylocalnetwork.example.com
           Compression no
         Host *
           Compression yes
       Alternatively specify "ssh -C" as your ssh command in your hgrc or
