+ * 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.
+ *
+ * If you want the update to be processed without restarting, set the restart
+ * parameter to false.
+ *
+ * This function does not modify appDir.
