   Assuming all the required gems install properly, verify you can run the `asciidoctor-pdf` script:
   
  
positive.code: :uri-rvm: http://rvm.io
  :uri-asciidoctor: http://asciidoctor.org
  
  // FIXME See last line; Asciidoctor should only be using outfilesuffix defined in header
  :original-outfilesuffix: {outfilesuffix}
  :outfilesuffix: .adoc
  
  _Lo and behold_, a native PDF converter for AsciiDoc built with {uri-asciidoctor}[Asciidoctor] and {uri-prawn}[Prawn]! +
  _No more middleman._ +
  _No more DocBook toolchain._ +
