// 1. Feeds added in code here. (None, at least for now.)
|

// 2. Default feeds for new users — see DefaultFeeds.plist.
|
||
// 3. FeedList.plist — the main directory. Its top level is all folders. There are no sub-folders.
|
||
// It’s okay if there’s overlap: a feed may appear in multiple places.
|
||
// If there’s any problem with the data (wrong types), this will crash. By design.
