/**
 * This function processes any available updates.  As part of that process, it
 * may exit the current process and relaunch it at a later time.
 *
 * 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.
