<?xml version="1.0"?>

Assuming the file is in the same folder than your source.

var gpf = require("./gpf.js");

Using NPM package

To install the gpf-js package use:

npm install gpf-js --save

Then, in your code, you can access the release version with:

var gpf = require("gpf-js");

Or the debug version with:

var gpf = require("gpf-js/debug");
