* Two directories are passed to this function: greDir (where the actual
* 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
* relaunch the current process.
*
* 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
* current application version.
*
* This function does not modify appDir.
