// Each file in the `deps` directory expresses the dependencies of a stub.
// For example, `deps/http.js` calls `require("http-browserify")` to
// indicate that the `http` stub depends on the `http-browserify` package.
// This makes it easy for a bundling tool like Browserify, Webpack, or
// Meteor to include the appropriate package dependencies by depending on
// `meteor-node-stubs/deps/http` rather than having to know how the `http`
// stub is implemented. Some modules in the `deps` directory are empty,
// such as `deps/fs.js`, which indicates that no dependencies need to be
// bundled. Note that these modules should not be `require`d at runtime,
// but merely scanned at bundling time.
