asciidoctor-multipage is an extension for Asciidoctor that adds a configurable multipage HTML converter. It extends the stock HTML converter to generate multiple HTML pages from a single document. For an example of this extension in use, see the NXLog User Guide in my portfolio.
The extension is published on RubyGems as asciidoctor-multipage. For more information, see the README in the Git repository for this project—currently hosted on GitHub at owenh000/asciidoctor-multipage.
