+%    This is a necessary initalization in order not to rebuild an existing font.
+%    Maybe 600 should be replaced by |\pdfpkresolution| or |texconfig.pk_dpi|
+%    (and it should be replaced dynamically), but we don't have access (yet) to
+%    the |texconfig| table, so we let it be 600. Anyway, it does still work
+%    fine even if |\pdfpkresolution| is changed.

+%    This is a patch for |otfl-font-def.lua|, that defines a reader for ofm
