+Dripping Water Mod
+by kddekadenz
+
+
+Installing instructions:
+
+	1. Copy the drippingwater mod folder into games/gamemode/mods
+
+	2. Start game and enjoy :)
+
+
+Manual:
+
+-> drops are generated rarely under crumbly nodes (dirt,grass,sandstone)
+-> waterdrops are generated under cloudstone massively
+-> they will stay some time at the generated block and than they fall down
+-> when they collide with the ground, a sound is played and they are destroyed
+
+
+License:
+
+code & sounds: CC0
+
+
+Changelog:
+
+16.04.2012 - first release
+28.04.2012 - drops are now 3D; added lava drops; fixed generating of drops (not at edges now)
