Module:Check for deprecated parameters
Ọdịdị
This module may be appended to a template to check for uses of deprecated parameters. The purpose is to locate deprecated parameters, display a message and place the page in a specific category noting that it is deprecated.
Note: due to the nature of deprecations, this module will often have no templates implementing it.
Usage
[dezie ebe o si]{{#invoke:check for deprecated parameters|check |category=[[Category:<category_name>|_VALUE_]] | old_param1 = new_param1 | old_param2 = new_param2 | .... | old_paramN = new_paramN }}
