[plt-scheme] Including example code from a file in Scribble

Thanks!  Note that Scribble barfs if every section (as included with
@include-section) doesn't contain a @title.  I don't know if this is
deliberate but it took me ages to work what was going wrong.

Here's the error message:

Welcome to MzScheme v370.6 [3m], Copyright (c) 2004-2007 PLT Scheme Inc.
 [Output to /home/pg/nhw/shared/zero-to-hero/zero-to-hero/index.html]
car: expects argument of type <pair>; given #f

/data/private/nhw/lib/plt/collects/scribble/html-render.ss:72:6:

And here's my build script:

(module build mzscheme

  (require (lib  "run.ss" "scribble")
           (file "zero-to-hero.scrbl"))

  (parameterize
      ([current-render-mixin multi-html:render-mixin]
       [current-dest-directory (current-directory)]
       [current-info-output-file "info-html.data"])
    (build-docs (list doc)
                (list "zero-to-hero")))

  )
