+#' the registry is loaded. This also reloads the cluster functions configured
+#' there, so changes to the configuration or to a referenced scheduler template
+#' can be applied by calling \code{loadRegistry()} again instead of recreating
+#' the registry.

+#' Only jobs submitted with \code{\link{submitJobs}} after reloading the registry

 #' Multiple R sessions accessing the same registry simultaneously can lead to database inconsistencies.
 #' This is especially dangerous if the same \code{file.dir} is accessed from multiple machines, e.g. via a mount.
