Fervor is a simple, multiplatform (Qt-based) application update tool, inspired by Sparkle.
Fervor is a software library that you include into your own Qt-based application in order to enable the application to automatically check for updates and suggest to install them.
At the moment, Fervor is not as cool as Sparkle -- it is not able to install the actual update automatically (the user is given an option to download and install the update manually)."
"There is only one thing i don't like - additional dependences from webkit and webkitwidgets.
But warning it is all i want to have now. We don't have power to test auto install feature."
