Template:Backlog navigation/doc

Shows the status of a backlog and, if it has dated subcategories that are over a week old, links to them.

For example, Category:Wikipedia files with unknown source has a few subcategories with names like "Wikipedia files with unknown source as of (some date here)‎". (The date refers to the upload date of the files in the category.) If the category for 8 days ago exists, this template will display the text "1-day backlog" and list the category in the collapsed box; for 9 days ago, 2-day; and so on up to 16 days, beyond which this template will simply say "Huge backlog".
