Note that the newsfeeds must contain either a pubDate or dc:date field for their items in order to correctly select the most recent stories:

require_once "/path/to/carp.php";

// don't display any channel fields

// display a bullet before each item
CarpConf('bi','&bull ');

// set up the filtering

// show up to 4 items

// show upt o 100 characters from the description

// refresh every 2 hours

// Filter each newsfeed and cache the results
CarpCacheFilter("", "agg2-slashdot");
CarpCacheFilter("", "agg2-infoworld");

// combine the results from the two newsfeeds
Example Output:

[CaRP] Can't open remote newsfeed [404].
