  # Create a database locally
  db_list(x)
  if ("hello_earth" %in% db_list(x)) {
    invisible(db_delete(x, dbname = "hello_earth"))
  }

  ## replicate to a remote server
  z <- Cushion$new(host = "example.com", transport = "https", port = NULL)

  ## do the replication
  db_replicate(x, z, dbname = "hello_earth")

  ## check changes on the remote
  db_list(z)
  db_changes(z, dbname = "hello_earth")

  ## make some changes on the remote
  doc_create(z,
    dbname = "hello_earth",
    '{"language":"python","library":"requests"}', "stuff"

    docid = "R_rules"
