ᱪᱷᱟᱸᱪ:Change parameter
Template documentationThis template maps one parameter name to another, but omits the parameter entirely if it's blank. Its first instance in a series must be prefixed with a pipe, and it must always be substituted. Its purpose is to convert transclusions of one template to another's.
{{Change parameter|{{{old parameter|}}}|new parameter name|default=a default value}}
