Where to look for ECKey.privateKeyPrefix on coins source

[yacare]

Hi all,

I see that many have adapted the bitaddress code for their coin. On the bitaddress code, the var that determines how the priv key prefix is "ECKey.privateKeyPrefix".

If I know the correct prefix for a particular coin, I can adapt the code to produce the priv key for that coin (if compatible) ...

My question is: Where on the source code (for WhateverCoin) should I look for that prefix?

Thanks.
