svm_light.rb is a Homebrew recipe for installing svmlight. It include a patch that adds a binary called svm_classifyd. This is basically a classifier which can run as a daemon and be communicated with over stdin/stdout, to avoid having to spawn new svm_classify processes.

To install:

$ brew tap contours/homebrew-alt
$ brew install svm_light
