RSS is a family of Web feed formats used to publish frequently
updated content such as blog entries, news headlines, and podcasts
in a standardized format. An RSS document (which is called a "feed"
or "web feed" or "channel") contains either a summary of content
from an associated web site or the full text. RSS makes it possible
for people to keep up with web sites in an automated manner that can
be piped into special programs or filtered displays.
