Basic routine for tool setter.

Hi everyone. 

I've purchased a tool setting probe for my 3 axis mill with a manual tool changer. I've been struggling with trying to find a simple routing that will allow me to set the tool Z offset for each of my tools. I'm posting this question as a last resort. 

The Mill uses a 7i76e Mesa card and I have the probe wired into one of the input pins and configured with probe-in in my hal file. Everything there works great. I can view the pin in the HAL utility and see the indicator change when I manually press the top of the probe. 

I've been struggling to find a routine that simply touches off each tool and sets the offset in the tool table.  T1 is my reference probe ( digital edge finder) and I'd like to reference all of my tools from that. Up until now I've been using the paper feeler gauge technique for T2 and beyond. 
Every example suggests complicated glade GUIs or installing a bunch of python stuff and the O-word snippets I've found so far don't work ( bad/old g-code maybe) The wiki seems out of date, too. 

So is there a simple routine that will help me? I don't need fancy GUIs.

Cheers and thank you for reading this far.

Thank you. The shop got a bit flooded here in Brisbane but I finally got this done and dusted.

The code in that thread worked a treat.
