{% comment %} TODO: For POSTS, currently the ASCIIDOC macro include:: does NOT work.
Path calculation needes to be fixed. Seems Jekyll is using different flavours
for page_path (post|pages).

{% comment %} Include directive (include::)
--------------------------------------------------------------------------------
// Note: The include directive looks like a >>block macro<< but it is a
// >>preprocessor directive<< like ifdef and ifeval. It gets processed
// before the lines are parsed into a document structure.
//
// If the path relative, the processor resolves the path using the following
// rules:
//
// If the include directive is used in the main (top-level) document,
// relative paths are resolved relative to the base directory. (The base
// directory defaults to the directory of the main document and can be
// overridden from the CLI or API).
//
// If the include directive is used in a file that has >>itself been included<<,
// the path is resolved relative to the including (i.e. current) file.

// NOTE: Calculation of Pathes
// Web sources are loaded by the Web Server. The location imagesdir
// is calculated relative to "web_root". Asciidoc resources are being
// collected by AsciiDoctor relative to "page_root"
