This module issubject to page protection. It is ahighly visible module in use by a very large number of pages, or issubstituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it isprotected from editing.
Module:Check for deprecated parameters may be appended to a template to check for uses of deprecated parameters. It will place the page in a specific category, and display a preview message, when it finds deprecated parameter uses.
Note: due to the nature of deprecations, this module will often have no templates implementing it.
