The Fedora Daily Package is an unofficial daily guide to some of the
interesting and useful packages in Fedora which installed by default. A
new package is featured each Weekday according to daily themes, except
for Wednesday, when the site features an in-depth look at a Fedora
packaging or configuration detail.
This is a fun and easy way to learn about new packages that you may have
never heard about! The Fedora daily Package is at
http://dailypackage.fedorabook.com (Atom and RSS feeds are available).
