Client with Auto Crafting?

Is there any client that has a feature where it auto crafts what you want, say you have a whole inventory of ingots and you want to turn them into blocks... etc.

(dont wanna use irl money to buy a rank just for /block :P)

Im like 90% sure WeepCraft has one, but weepcraft sucks so :/

I don't think it's actually possible, considering the API used in crafting.
I could be wrong though

Use a mod called MacroMod and use this script:
$${CRAFT($$i,$$[999])}$$

The only one I know is weep craft.
