  A letter, not a chapter: a wider measure, with a dateline and a hand at
  the end. Front matter it reads besides `title`:

    dateline:  a date or a place and a date  (optional)
    signature: the name under the last line  (default "Jorge")
    signature_url: where the name links to     (optional)
    postscript: a line after the signature   (optional)

  The body starts at the first paragraph; no headings are needed, and `##`
  headings, if any, are set as section breaks rather than titles.
