I added some additional information about SyncTex and the required parser.
Please have a look at:
http://ctan.org/tex-archive/support/synctex-parserDifferent pdf viewers like pdf.js, evince, okular, skim, Sumatrapdf, texstudio, texworks etc. support already synctex.
Generating a pdf file with asciidoctor-pdf and re-use of synctex could be really beneficial for most of the user who are writing books etc.
I would be really interested in the feedback of other users and would like to know how others handle and maintain asciidoc files with several hundred pages without having a viewer with dual page view and synchronization with the source file.
