मोड्युल:Check for deprecated parameters

मोड्युल कागजात[हेर्नुहोस्] [सम्पादन गर्नुहोस्] [इतिहास] [ताजा गर्नुहोस्]

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

{{#invoke:check for deprecated parameters|check
|category=[[Category:<category_name>|_VALUE_]]
| old_param1 = new_param1 
| old_param2 = new_param2
| ....
| old_paramN = new_paramN
}}
