+%D \macros
+%D   {averagecharwidth, charwidthlanguage}
+%D
+%D This is a more \MKIV-ish variant of lang-frq.mkiv. The methods are
+%D gone as one doesn't need the tables for them. The main macro is
+%D \type {\averagecharwidth} which behaves like a dimension register.
+%D
+%D I finally decided to reimplement this as I needed it for a manual
+%D (which is often a reason for such a rewrite). With some inspiring
+%D Porcupine Tree in the background it's not the worst thing to do.
