/**
* This function processes any available updates. As part of that process, it

* binary resides) and appDir (which contains application.ini for XULRunner
* apps). If this is not a XULRunner app then appDir is identical to greDir.
*
* The argc and argv passed to this function should be what is needed to

*
* The appVersion param passed to this function is the current application's
* version and is used to determine if an update's version is older than the
