Conversion of Pandoc documents to asciidoc.

Note that some information may be lost in conversion, due to expressive limitations of asciidoc. Footnotes and table cells with paragraphs (or other block items) are not possible in asciidoc. If pandoc encounters one of these, it will insert a message indicating that it has omitted the construct.
