-# formation        *** DEPRECATED ***
-# =============================================================================
-# A modification of the livery class. This class maintains formation
-# XML files (see Blackburn Buccaneer for an example). Files are regular
-# PropertyList XML files whose properties are copied to the
-# main tree (whereby the node types are ignored).
-#
-# SYNOPSIS:
-#	formation.init(<formation-dir> [, <name-path> [, <sort-path>]]);
-#
-#	<formation-dir> ... directory with livery XML files, relative to $FG_ROOT
-#	<name-path>     ... property path to the livery name in the livery files
-#	                    and the property tree (default: /sim/model/formation/name)
-#	<sort-path>     ... property path to the sort criterion (default: same as
-#	                    <name-path> -- that is: alphabetic sorting)
-#
-# EXAMPLE:
-#	aircraft.formation.init("Aircraft/Buccaneer/Formations",
-#	                        "sim/model/formation/variant",
-#	                        "sim/model/formation/index");  # optional
-#
-#	aircraft.formation.dialog.toggle();
-#	aircraft.formation.select("take off");
-#	aircraft.formation.next();
