List of historic output locations for files in the collection

The first element is the canonical location.

All other elements are used to create redirects to the canonical location.

The default entry is the symbolic name of the collection.

When changing the symbolic name, append the old one to your custom list and use `lib.mkForce` to make sure the default element will be overridden.
