+;;; Another variant of the web book publishing. This module is purely
+;;; functional, i.e., unlike `web-book', it doesn't modify the HTML engine
+;;; customs or writers. Instead, it replaces the `chapter' and
+;;; `(sub)*section' markups with variants that produce a small table of
+;;; contents at the beginning of new files.

+
