   The Document and Section templates should begin with +document.+ and +section.+, respectively.
   The file extension is used by Tilt to determine which view framework it will use to render the template.

  == AsciiDoc Processing
  
  // QUESTION Remove this section with an image ?
  
  Asciidoctor reads and parses AsciiDoc markup (from a file or string) and feeds the parsed result to a set of built-in templates to render the document as HTML 5, DocBook 4.5 or DocBook 5.0.
  Asciidoctor is a drop-in replacement for the original AsciiDoc processor.
  We've matched the output to that produced by the AsciiDoc Python processor as faithfully as possible.
  You can override the built-in templates, or produce a custom format, by pointing the processor at a set of template files written in a language supported by {tilt}[Tilt].
  See the <<usage>> section for more details.
  
  // QUESTION Can we capture the number of tests and assertions in Travis CI and display the result below the "build status" ?
  
  NOTE: With few exceptions, Asciidoctor is compliant with the original AsciiDoc processor.
  Asciidoctor has well over 1,000 tests to ensure compatibility with the AsciiDoc syntax.
  We continue to work hard to ensure Asciidoctor continues to serve as a drop-in replacement for AsciiDoc.
