+brings Gnus-style scoring to your RSS feeds.  Elfeed, by default, displays
+feed entries by date.  This package allows you to setup rules for assigning
+numeric scores to entries, and sorting entries with higher scores ahead of
+those with lower, regardless of date.  The idea is to prioritize content
+important to you.")
