+// The targets here are a bit different than for most pages: rather than data
+// objects loaded from text files in the wiki data directory, they're hard-

+// and turning it into user-readable HTML listings.
+//
+// Individual listing specs are described in src/listing-spec.js, but are
+// provided via wikiData like other (normal) data objects.
