+It is inspired by already existing TeXcount for LaTeX. The functionality is
+really lightweight and basic.  It counts words and other elements of OpTeX
+document and sorts them out into individual categories.  Users can print the
+source code with highlighted words using several colors, so they see what is
+considered as word, header etc.")
