Thanks to Marcin Zajączkowski, Jubler is available for Fedora too.

I am making some serious changes on the Jubler source code and I am looking for brave young persons to try Jubler and see if everything works as expected!
I will release 3.3 soon and due to lack of time, I don't have the time luxury to test Jubler.
If anyone is interested, please contact me by email or in the forum.
