Usage

{{documentation subpage}}

OR

 {{documentation subpage|[[main page to link to]]|[[documentation to link to]]}}

This template should be placed at the top of "/doc" pages. It changes output depending on where it is viewed:

On a "/doc" page, it displays a box explaining template documentation and links to the template page.
On other pages (ie, pages transcluding the "/doc" page), it notes that the documentation is transcluded from a subpage.

Functions

In addition to the output message, the template categorizes pages to Category:License template documentation. It defaults the sort key to the page name without namespace (ie, "Foo" on "Template:Foo", so it would be sorted in categories under 'F').
