Use Node.js as standalone LESS-compiler in project?
node compiler.js build.js

({
    baseURL : "../assets",
    mainConfigFile : "../assets/main.js",
    name : "../assets/main",
    out : "../assets/main.optmin.js",
    optimize : "uglify"
})

node path/to/less/bin/lessc -x -O2 path/to/assets/main.less > path/to/output.css
