If you want the newest version of the reader,
1. In the directory River5 is running in: npm update
2. Relaunch river5.js.
It should now say it's running River5 0.5.16.
It now maintains a river for each of the feeds you're subscribed to.
This should make it possible to have a reverse-chronologic view of items from a single feed.
A sort of simple mailbox reader function.
