This module is rated as ready for general use. It has reached a mature form and is thought to have only few to no bugs and is ready for use wherever appropriate. It is ready to mention on help pages and other essential Wikipedia resources as an option for new users to learn. To reduce server load and bad output as well as confusion, it should be improved by sandbox testing rather than repeated trial-and-error editing.
This module is subject to page protection. It is a highly visible module in use by a very large number of pages, and/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 protected from editing.
This module implements Ta̱mpi̱let:Lt. Please see the template page for documentation.
