testfeed.php [options] http://example.com/atom-feed-url
Pull an Atom feed and run items in it as though they were live PuSH updates.
Mainly intended for testing funky feed formats.

     --skip=N   Ignore the first N items in the feed.
     --count=N  Only process up to N items from the feed, after skipping.
