+--Simple lua OS examples by Paul Hedderly
+-- PREREQUISITES:
+-- 	luarocks install luasocket # optional if you will use your own connectors (see below)
+-- 	luarocks install luabitop  # you don't need this for lua 5.3
+-- 	luarocks install luasec    # you don't need this if you don't want to use SSL connections
+-- 	luarocks install luamqtt
+
+-- Example - A lot of these will depend on other configs and will need to be localised
+-- 	[lua i3msg]
+--	script = confgs/i3msg.lua
+--	default-handler = i3msg
+--
+--		nanomap.{1..10} > i3msg.workspace.{1..10} -- Jump to i3 workspace
