Template:Topic cat/sandbox
本模板應該用於Category:命名空間頁面,and automatically generates descriptions and categorization for categories of a recognized type (see below). It is implemented by Module:category tree and its submodule Module:category tree/topic cat. It is preferable not to invoke this template directly, but to simply use {{auto cat}}
(with no parameters), which will automatically invoke this template on appropriately-named category pages.
