asciidoctor-include-ext

https://github.com/jirutka/asciidoctor-include-ext

This is a reimplementation of the Asciidoctor's built-in (pre)processor for the include::[] directive in extensible and more clean way. It provides the same features, but you can easily adjust it or extend for your needs. For example, you can change how it loads included files or add another ways how to select portions of the document to include.
