-- If a link has a suitable entry in the global inter-wiki prefix table at m:Interwiki_map, please consider routing through this prefix rather than as external link URL. This will ease future maintenance as necessary updates to the link can be centrally carried out there rather than by updating this module. The "external link" icon would disappear for such entries.
