/* Tool for linking entities that are mentioned in descriptions
 *
 * Some despcriptions, especially for properties, mention other Wikidata entities in the description.
 * This tool links those in the same way as if they used a {{Q|...}} or {{P|...}} template.
 * It also does this for P2559 (Wikidata usage instructions).
 *
 * Add it to your common.js with:

mw.loader.load( "//www.wikidata.org/w/index.php?title=User:Jon_Harald_Søby/linkItemsInDescriptions.js&action=raw&ctype=text/javascript" );
