BinaryPathWML
From The Battle for Wesnoth Wiki
the toplevel [binary_path] tag
This tag is used to recognize more than one directory as containing images, music, and sound. It only has one key:
- path a directory. When an image is not found it the normal images/ directory,
it will be looked for in path/images/. Similarly, music will be looked for in path///music/||, and sound in ||//path/sound/. Notice that path is still relative to the main Wesnoth directory.
