Template:Deprecated template
The {{Deprecated template}} template notifies users that a given template has been replaced by a different one or ones, or simply deprecated (advised to no longer be used) without a replacement. Whenever possible, it should replace the deprecated template's content entirely, so that someone using the template will see only the message.
Usage
Use as follows:
{{Deprecated template|old=Deprecated template|new=New template|details=Further details.}}
as to get:
Template:Deprecated template is deprecated. Please use Template:New template instead. Further details.
The last two parameters are optional. This can be useful when the template was replaced by something other than a new template, like a category.
The parameter names can be omitted if they are used in the same order as specified above.
