“size” may be a number specifying the file size in bytes, or a string specifying a local file path. If the local file exists, its file size is used.

“source” may be a local file path or an HTTP/HTTPS URL.

“maxage” and “maxcount” affect only appcast entries in the current release track. Appcast entries in other tracks and non-appcast entries in the XML feed are not removed.
