anchor.diff:  
   For example, let's assume you've defined the following settings in your theme:
   
  -[source,yaml]
  +[,yaml]
   ----
   page:
     margin: [0.5in, 0.67in, 0.67in, 0.67in]
  
positive.code: Other "`facing`" pages may be added in the future.
  
  It's possible to disable the automatic facing feature for a given part or chapter.
  This can be done by adding the nonfacing option to the section node.
  When the nonfacing option is present, the part or chapter title will be placed on the next adjacent page rather than the next facing page.

  [%nonfacing]

  TODO: Issue 95 is solved, this should be deleted
  
  For documents that use the article doctype, Asciidoctor PDF incorrectly places the document title and table of contents on their own pages.
  This can result in the page numbering and the page facing to be out of sync.
  As a workaround, Asciidoctor PDF inserts a blank page, if necessary, to ensure the first page of body content is a recto-facing page.
  
  You can check on the status of this defect by following https://github.com/asciidoctor/asciidoctor-pdf/issues/95[issue #95].

negative.code: 
  Asciidoctor PDF provides the following behaviors to assist with printing:
  
  * Shows the URLs for links unless the linked text matches the URL
  * Consolidates page ranges in the index
  * Deactivates the links from page numbers in the index to the locations of terms in the document
  
  To enable these printing features, set the `media` document attribute to `print` in the header of your AsciiDoc document or from the API or CLI (e.g., `-a media=print`).
  You may also want to consider using the print-optimized theme, which uses darker, grayscale colors for text and borders (e.g., `-a pdf-theme=default-for-print`).
  
  [#prepress]
  == Prepress mode
  
  In addition to the <<print,print mode>>, Asciidoctor PDF provides the following behaviors to assist with publishing:
  
  * Double-sided (mirror) page margins
  * Automatic facing pages
  
  Set the `media` attribute to `prepress` in the header of your AsciiDoc document or from the API or CLI (e.g., `-a media=prepress`) to activate the publishing features.
  The following sections describe the behaviors that this setting activates.
  You may also want to consider using the print-optimized theme, which uses darker, grayscale colors for text and borders (e.g., `-a pdf-theme=default-for-print`).
