#' Operating System
#'
#' Determine operating system name.
#'
#' @return
#' \code{os} returns the name of the operating system, typically \code{"Linux"},
#' \code{"Darwin"}, or \code{"Windows"}.
#'
#' \code{os.linux}, \code{os.macos}, \code{os.unix}, and \code{os.windows}
#' return \code{TRUE} or \code{FALSE}.
#'
#' @note
#' The macOS operating system identifies itself as \code{"Darwin"}.
#'
#' Both Linux and macOS are \code{os.unix}.
#'
#' These shorthand functions can be useful when writing workaround solutions in
#' platform-independent scripts.
#'
#' @seealso
#' \code{\link{Sys.info}} is the underlying function used to extract the
#' operating system name.
#'
#' \code{\link{TAF-package}} gives an overview of the package.
