APM to CHDK camera - stale guideline

I tried following the guideline on APM to CHDK Camera Link Tutorial (*). The guideline has references to APM-parameters which I can not find on APM 2.5 firmware Arducopter 3.0.1. Teh parameters in question are: CAM_TRIGG_DIST and RELAY_PIN Without them the guideline is pointless.

I see the changes will let the folks know.
