| 731a82 | 2 | Wrench mod |
| S | 3 | |
| 4 | Adds a wrench that allows the player to pickup nodes that contain an inventory | |
| 5 | with items or metadata that needs perserving. | |
| 6 | The wrench has the same tool capability as the normal hand. | |
| 7 | To pickup a node simply right click on it. If the node contains a formspec, | |
| 8 | you will need to shift+right click instead. | |
| 0cf413 | 9 | Because it enables arbitrary nesting of chests, and so allows the player |
| Z | 10 | to carry an unlimited amount of material at once, this wrench is not |
| 11 | available to survival-mode players. | |
