--- snowdrift 0.3.0 by paramat
--- For latest stable Minetest and back to 0.4.9 dev after 13/01/14

--- update particle spawn format

--- Parameters
-
-local SCALP = 4 -- Time scale for precipitation in minutes
-local PRET = 0.3 -- -1 to 1. Precipitation threshold: 1 none, -1 continuous, -0.3 two thirds the time, 0 half the time, 0.3 one third the time
-local PPPCHA = 0.1 -- 0 to 1. Per player processing chance. Controls and randomizes processing load
-local SETCHA = 0.1 -- 0 to 1. Snow settling chance
-local FLAKES = 1 -- Snowfall heaviness. Try 1 on slower computers
-local DROPS = 2 -- Rainfall heaviness. Reduce on slower computers
-local SNOW = true -- Snowfall below temperature threshold
-local SETTLE = false -- Snow collects on ground within 32 nodes of player
-local RAIN = false -- Rain above humidity threshold
-local THOVER = false -- Instead use a temperature and humidity system with
-			-- snow in overlap of cold and humid areas, else rain in humid areas
-
--- Temperature noise parameters
-local SEEDT = 112 -- 112 These are default noise parameters from snow mod by Splizard
-local OCTAT = 3	 -- 3		use these for snowfall in those snow biomes
-local PERST = 0.5 -- 0.5
-local SCALT = 256 -- 150, modified for Watershed
-local TET = -0.53 -- -0.53 Temperature threshold for snow. Negative because here this noise is temperature, in snow mod it's coldness
-
--- Humidity noise parameters
-local SEEDH = 72384 -- 72384 These are default noise parameters for mapgen V6 humidity
-local OCTAH = 4 -- 4		note these cause rain in deserts
-local PERSH = 0.66 -- 0.66
-local SCALH = 256 -- 500, modified for Watershed
