+;
+; Mode:
+;
+;    ON_AGL_DEVEL(DEVEL, RELEASE)
+;
+; Role:
+;
+;    Configure how installation of widget produces unit files for systemd
+;
+; Processing and format:
+;
+;    1. File load
+;
+;           Lines beginning with ; are firstly removed
+;
+;    2. File instantiation
+;
+;           Mustache (extended) substitutions are applied using JSON
+;           data deduced from config.xml file of the widget.
+;
+;    3. Extraction of units
+;
+;           Extract produced units, pack it (remove empty lines and directives)
+;
+; Directives:
+;
+;    Any directive occupy one whole line starting with %
+;
+;     - %nl
+;
+;             produce an empty line at the end
+;
+;     - %begin systemd-unit
+;     - %end systemd-unit
+;
+;             delimit the produced unit
+;
+;     - %systemd-unit user
+;     - %systemd-unit system
+;
+;             tells the kind of unit (user/system)
+;
+;     - %systemd-unit service NAME
+;     - %systemd-unit socket NAME
+;
+;             gives the name and type of the unit
+;
+;     - %systemd-unit wanted-by NAME
+;
+;             tells to install a link to unit in the wants of NAME
+;
+; Setting variables:
+;
+;    AFM uses the feature of systemd that completely ignores options prefixed
+;    with X-
+;
+;    Consequently, options starting with X-AFM- are recorded as public data
+;    about the application and options starting starting with X-AFM-- are
+;    recorded as private data.
+;
+;    Examples:
+;
+;        X-AFM-description={{description}}
+;
+;              Records the description of the unit in the field "description"
+;              of both the public and private object describing the unit.
+;
+;        X-AFM--wgtdir={{:#metadata.install-dir}}
+;
+;              Records the installation directory path in the field "wgtdir"
+;              of the private object only.
