 | This Lua module is used on 238,000+ pages. To avoid large-scale disruption and unnecessary server load, any changes to this module should first be tested in its /sandbox or /testcases subpages. The tested changes can then be added to this page in one single edit. Please consider discussing any changes on the talk page before implementing them. |
This module implements {{URL}}. Please see the template page for documentation.
