+		Asciidoctor PDF is a native PDF converter for AsciiDoc that serves the
+		pdf backend. It bypasses the step of generating an intermediary format
+		such as DocBook, Apache FO, or LaTeX in order to produce PDF.
+		Instead, you use Asciidoctor PDF to convert your documents directly
+		from AsciiDoc to PDF with Asciidoctor. The aim of this library is to
+		take the pain out of creating PDF documents from AsciiDoc.
