Multiple underlays are normally set up automatically by other plugins (for
-instance, the images used by the [[plugins/smiley]] plugin), but they can also be

-Directories in `add_underlays` should usually be absolute. If relative, they're
-interpreted as relative to the parent directory of the basewiki underlay, which
-is probably not particularly useful in this context.
