Sorry, you called it with -h, I hadn't realised the vast extent of your research. If you think this is an acceptable amount of work I suggest changing careerer/course ASAP. You've been a member here since 2005, you've posted hundreds of times. At some point you're actually going to have to do some work of your own. If you can't work out what Gungho does based on the resources available, what is your next step going to be?
