+#' Provide a singular interface for hook calls to docopt
+#'
+#' docopt provides different processing for a single string
+#' than an array/vector. As `"string"`` and `c("string")`
+#' are semantically equivalent in R, this can create problems
+#' when a single parameter is provided. Thus, this function
+#' wraps docopt to ensure that the args will always be
+#' interpreted as a vector.
+#'
+#' This function is only exported for use in hook scripts, but it's not intended
+#' to be called by the end-user directly.
+#' @param doc `character` vector with command line specification.
+#' @param args `character` vector of command line arguments.
+#'   Defaults to `commandArgs(trailingOnly=TRUE)`.
+#' @param ... Additional parameters passed to `docopt`.
+#' @family hook script helpers
