23%D This is a more \MKIV-ish variant of lang-frq.mkiv. The methods are gone as one
24%D doesn't need the tables for them. The main macro is \type {\averagecharwidth}
25%D which behaves like a dimension register.
26%D
27%D I finally decided to reimplement this as I needed it for a manual (which is often
28%D a reason for such a rewrite). With some inspiring Porcupine Tree in the
29%D background it's not the worst thing to do. The \LMTX\ variant is a bit more
30%D flexible as it can also set, not that someone will notice.
