This is an fstream DirReader class that will read a directory and filter things according to the semantics of what goes in an npm package.
For example:
// This will print out all the files that would be included // by 'npm publish' or 'npm install' of this directory. var FN = require("fstream-npm") FN({ path: "./" }) .on("child", function (e) { console.error(e.path.substr(e.root.path.length + 1)) })
