This module causes an error if any nil global is read or if any global is written to, with the exception of arg. To use, add to the top of the module using it. The arg variable is excluded because it is necessary for Scribunto's require function to work properly. (See the Scribunto source code here.)
Module documentation

This template is used on 4,000,000+ pages. To avoid large-scale disruption and unnecessary server load, any changes to this template should first be tested in its /sandbox or /testcases subpages, or in your own user space. 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 is subject to page protection. It is a highly visible module in use by a very large number of articles, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is is protected from editing. |
