-- More trees! 2013-04-07
--
-- This mod adds more types of trees to the game
--
-- Some of the node definitions and textures came from cisoun's conifers mod
-- and bas080's jungle trees mod.
--
-- Brought together into one mod and made L-systems compatible by Vanessa
-- Ezekowitz.
--
-- Firs and Jungle tree axioms/rules by Vanessa Ezekowitz, with the
-- latter having been tweaked by RealBadAngel, most other axioms/rules written
-- by RealBadAngel.
--
-- License: WTFPL for all parts (code and textures, including those copied
-- from the jungletree and conifers mods) except the default jungle tree trunk
-- texture, which is CC-By-SA.
moretrees = {}
-- If the config file is not found in the world directory, copy the default
-- settings to that location and read them in.
