This template uses Lua: Module:See also if exists (sandbox)

Displays a "see also" link to one or more categories, if the category exists. If none of the supplied categories exists, the template does nothing.

It allows the creation of links to categories which do not yet exist, but which will be displayed if and when the category is created. This is useful as a category tree is being developed, because the editor does not have guess whether a target category is likely to exist any time soon. The link can be created now, rather than having to edit the page again later.
