Curn
public class Curn (Code)

curn: Customizable Utilitarian RSS Notifier.

curn is an RSS reader. It scans a configured set of URLs, each one representing an RSS feed, and summarizes the results in an easy-to-read text format. curn keeps track of URLs it's seen before, using an on-disk cache; when using the cache, it will suppress displaying URLs it has already reported (though that behavior can be disabled). curn can be extended to use any RSS parser; by default, it uses the ROME parser.

The Curn class represents the API entry point into the curn processing. Any program can call a Curn object's Curn.processRSSFeeds processRSSFeeds() method to invoke a curn run. In practice, most people use the existing Tool command-line program.
