// 1. Feeds added in code here. (Evergreen News should be the only one.)

// 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.
