docs: Take  a HTML  file `filename.html`  and combine  all the  styles in
  `css/@filename.css` and  all the javascripts  in `js/@filename.js`.
  For each module, check if there is  a folder with the same name. If
  yes, copy  that resource  in `css`  dir. For  example, it  you have
  `mod/foobar.js`   and   a   folder  `mod/foobar/`,   copy   it   to
  `www/css/foobar/`.
