+Since recent versions of Minetest no longer contain jungle biomes, and 
+hence no jungle grass, I created this mod to re-add said grass back into 
+the game, with a twist: There are now four different sizes of grasses, 
+all of which yield a single junglegrass object when gathered (so all 
+four sizes may be used where jungle grass is called for).  The largest 
+size uses the game's standard jungle grass node, while the others are 
+defined by this mod.
+
+Junglegrass will spawn on dirt, grass, sand, desert sand and the tops of 
+papyrus and cactus (though rarely), and will do so anywhere in the map.  
+Grass on the ground will grow and eventually die (or turn into dry 
+shrubs, in the desert), given enough time.
+
+Adjusting the overall spawn/growth rate is easily done by tweaking the 
+MAX_RATIO variable at the top of init.lua.  A larger value results in 
+less frequent events.
+
+Dependencies: none (just the game's default stuff)
+
+License:  cc-by-sa 3.0 for the textures, WTFPL for everything else.

+Changelog
+---------
+
+2012-08-03: Mild rewrite to adapt the mod to use perlin noise while spawning. 
+Also got rid of the random-numbers-inside-abm stuff, now using the abm's own 
+'chance' parameter instead.  Tuned various settings to try to retain the same 
+overall density and growth rates as in the previous version.  Moved this 
+changelog into a separate file.
+
+2012-07-12: moved project to github.
+
+2012-07-09 (a bit later): tuned the spawn/grow rates a bit more, made the 
+numbers more sane.  Added a radius check to limit the density of the spawned 
+grasses (they won't grow near each other or near dry shrubs or cactus, though 
+they still grow on the top of said cacti).
+
+2012-07-09: Added cactus, sand, and desert sand as spawning surfaces.  Reduced 
+and tuned the spawn rates a bit to try to balance things out.  Made that which 
+spawns on grass, dirt, or sand start out at any size, grow over time, and 
+eventually die off.  Limited desert sand to only the first two sizes (the 
+smallest size will grow one step, eventually), which will eventually die and 
+turn into dry shrubs.  Only the two smallest sizes can spawn on cactus or 
+papyrus (and they don't grow or die).  Fixed slightly off-center smallest size.  
+Fixed selection boxes.
