+Item Frames mod for minetest
+
+This mod differs from Zeg's original and the one included in homedecor modpack in that no one person owns the itemframe or pedestals, they are protected with minetest.is_protected() so can have multiple owners or none at all...  Items that have a light source will glow when placed in frames/pedestals.
+
+Right-click to add or remove an item from a frame or pedestal, please note that if an item already has on_rightclick registered then it cannot be added to either.  Punch frame or pedestal to force update if items do not appear.
+
+Itemframes can be rotated with a screwdriver which includes sitting flat on a surface, punch to update item inside.  You can also hold sneak and punch to rotate item inside frame.
+
+License was originally WTFPL although the codebase has changed so much I've reclassified as MIT License for simplicity and school use, and textures are CC-BY-3.0.
+
+
+Settings
+--------
+
+Change 'itemframes.return_item' setting to true if you want items to drop back into player inventory when removed (thanks fluxionary).
+
+Change 'itemframes.log_actions' setting to true if you want to log player actions when inserting or removing items from a frame or pedestal.
+
+Itemframe items can be rotated by holding sneak and punching frame, but in a protected area this is limited to the owner unless "itemframes.allow_rotate" setting is true.
+
+
+Texture Override
+----------------
+
+If a node has the _itemframe_texture string set then the itemframe will show that image instead of the item's own wielditem (mainly for 3d items that may not look good in frames) e.g.
+
+This shows furnaces inside an itemframe as a flat image:
+
+minetest.override_item("default:furnace", {
+	_itemframe_texture = "default_furnace_front.png"
+})
+
+This shows furance inside an itemframe as a 3D styled flat image:
+
+minetest.override_item("default:furnace", {
+	_itemframe_texture = minetest.inventorycube(
+		"default_furnace_top.png",
+		"default_furnace_side.png",
+		"default_furnace_front.png")
+})
