+This library is a simple RSS2 parser and RSS reader web
+application. To run the web application you'll need to make sure you
+have the sqlite library working. This can be tested with
+
+  "sqlite" require
+  "sqlite" test-module
+
+Remember that to use "sqlite" you need to have done the following
+somewhere:
+
+  USE: alien
+  "sqlite" "/usr/lib/libsqlite3.so" "cdecl" add-library
+
+Replacing "libsqlite3.so" with the path to the sqlite shared library
+or DLL. I put this in my ~/.factor-rc.
+
+Before running the RSS reader web application you need to create the
+history database in the same directory as the 'f' executable. Create
+it with:
+
+  sqlite3 history.db
+  > create table rss (url text, title text, link text, primary key (url));
+  > create table entries (url text, link text, title text, description text, pubdate text, primary key(url, link));
+  > [eof]
+
+To load the web application use:
+
+  "rss" require
+
+Fire up the web server and navigate to the URL:
+
+  http://localhost:8888/responder/maintain-feeds
+
+Add any RSS2 compatible feed. Use 'Update Feeds' to retrieve them and
+update the sqlite database with the feed contains. Use 'Database' to
+view the entries from the database for that feed.
