This plugin has been assimilated into calibre as from version 1.32! No need for you to download this anylonger 
I didn't want to manually import my 100+ RSS feeds from feedly, so I wrote this plugin.

Main Features
Import RSS feeds as an OPML file from feedly or google reader.
This plugin will create a recipe for each group and each remaining feed.
So far a restart is required to have the imported RSS feeds show up in custom news sources.
Version History
Special Notes
Requires calibre version 0.7.53 or later. This plugin has been assimilated into the main calibre code base as from version 1.32!
A restart is still required once the RSS feeds have been imported!
I forgot to add a 'Import finished' message box when the import completes, that's for tomorrow.

Download the attached zip file, install the plugin and restart calibre as described in the Introduction to plugins thread.
