 # Liquid PROCEDURE to setup the Asciidoc attributes for an (entry)
 # document. Initializes the all include paths for folders: images,
 # documents and tables

 # Usage:
 #  1)  capture the 'load_attributes' variable by full path
 #  2)  include|configure the load_attributes procedure
 #
 # Example:
 #  {% capture load_attributes %}themes/{{site.template.name}}/procedures/global/attributes_loader.proc{%endcapture%}
 #  {% include {{load_attributes}} scope="global|local|all" %}
 # -----------------------------------------------------------------------------
 # NOTE:
 #  Default:  scope="global"
 # -----------------------------------------------------------------------------
 # NOTE:
 #  Include directive (include::)
 #
 #  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 "_site" (web root). Asciidoc resources
 #  are being collected by AsciiDoctor relative to "page_root".
 # -----------------------------------------------------------------------------
 # 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 (for posts and pages).
 # -----------------------------------------------------------------------------
 # Test data:
 #  liquid_var:  {{ liquid_var | debug }}
