Ohai, I'm proud to announce you the first release of FeedsTail.
The aim of this program is to read and display a RSS/Atom feed and to display it like a tail -f would do it on a file. This behavior allow a lot of stream scripting.

You can find all the technical details and how to install it on the pypi page.
Thanks to the excellent feedpaser library, Feedstail is already very stable. It won't crash on disconnections or XML errors. If the feed structure doesn't change and your formating string (the -f option) doesn't rely on elements that may not be presents you can expect feedstail to run safely for severals days. But it's still the first release so don't hesitate to send bug report!
