Well... The auto-generated entries are sth like this:
Code
#Tiny Pile of Gunpowder:
S:gt.metaitem.01.800.name=Tiny Pile of %material
#Tiny Pile of Blaze Powder:
S:gt.metaitem.01.801.name=Tiny Pile of %material Powder
#Tiny Pile of Wood Pulp:
S:gt.metaitem.01.809.name=Tiny Pile of %material Pulp
#Tiny Pile of Chad:
S:gt.metaitem.01.879.name=Tiny Pile of Chad
#Other trivial cases. Take redstone for example:
S:gt.metaitem.01.810.name=Tiny Pile of %material DustDarkForce It's not necessary to use the placeholder. If a localized string doesn't contains the "%material" placeholder, it will be used directly as the name of the item. Thus it's even compatible with the lang file in earlier version.
