Package zeroinstall :: Package injector :: Module background

Module background

Check for updates in a background process. If we can start a program immediately, but some of our information is rather old (longer that the config.Config.freshness threshold) then we run it anyway, and check for updates using a new process that runs quietly in the background.

This avoids the need to annoy people with a 'checking for updates' box when they're trying to run things.

Classes
