I've temporarily post-poned making a human civ and chosen to make the reactions first, since it's a lot simplier.
So this is my workshop

No idea what it looks like... yet, I took it from some old modding page about rocks. Meh.
And this is what I have of the first reaction (corpses to leather)
Again, this is not balanced in any way but if I get this to work I can easily get all other reactions. And hey, it's a personal mod for myself, let an idiot have his fun.
[REACTION:GET_COPPER]

[PRODUCT:100:1:BAR:<material token>][...modifiers...][PRODUCT_DIMENSION:X][PRODUCT_TO_CONTAINER:<IDENTIFIER>]
As you can see I'm having trouble with PRODUCT, especially the Material token.
I've tried looking here
http://df.magmawiki.com/index.php/DF2010:Material_tokenBut there's no mention of copper or any other metals.
I ran into similar issues trying to produce leather instead of copper.
Where are the butcher reactions? I'd like to copy from them but I can't seem to find them.
