class_docstr: Create a dataset sibling on a UNIX-like Shell (local or SSH)-accessible machine
  
  Given a local dataset, and a path or SSH login information this command
  creates a remote dataset repository and configures it as a dataset sibling
  to be used as a publication target (see `publish` command).
  
  Various properties of the remote sibling can be configured (e.g. name
  location on the server, read and write access URLs, and access
  permissions.
  
  Optionally, a basic web-viewer for DataLad datasets can be installed
  at the remote location.
  
  This command supports recursive processing of dataset hierarchies, creating
  a remote sibling for each dataset in the hierarchy. By default, remote
  siblings are created in hierarchical structure that reflects the
  organization on the local file system. However, a simple templating
  mechanism is provided to produce a flat list of datasets (see
  --target-dir).
