From 0219d4fb9cefcee635387b46fc1d215f82753d92 Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Tue, 22 Dec 2015 17:03:01 +1300 Subject: recipetool: create: set up priority system for recipe handlers Sometimes we want to force one handler to run before another; if the two handlers are in different plugins that's difficult without some kind of priority number, so add one and sort by it.
