+of tokens.  Two mechanisms for defining chunks are provided: the
+@code{\\ranToks} command accepts an argument containing tokens to be
+randomised; and the @code{\\bRTVToks/\\eRTVToks} commands delimit a collection
+of tokens for randomising; each group inside a @code{rtVw} constitutes one of
+these (typically larger) token sets.")
