I'm looking for a a settings file in Homebrew for OS X that controls the build settings, similar to make.conf in Gentoo.
I want to tweak the make -j parameter to use more cores of my machine. The problem is, I can't find anything useful related to brew in /usr/local/etc. Is there a simple answer to this?

As @jakev said, each Homebrew formula is a separate Ruby script. You can find them at
https://github.com/mxcl/homebrew/tree/master/Library/Formula
If you want to edit the way a specific formula builds, you can do that locally. The following will open your default editor with the locally cached formula.
brew edit name-of-formulaThe reason for the absence of global build settings is simply that each formula might build in different ways, and editing yourself ("homebrewing") is explicitly encouraged.

That's an interesting design decision, since it would make sense to store some parameters, such as the "-j" build option globally. MacPorts seems more structured (if less flexible) in this sense. – Koffiman – 2012-10-29T16:00:26.817
1Each brew has its own recipe for making. These are usually ruby files, IIRC. You can certainly customize them, but there are no system wide homewbrew settings that I know of. – jakev – 2012-10-26T17:17:42.693
