+# Hot Pocket javascript client library and examples
+
+Single-file javascript library to support json and bson protocols in NodeJs and Browser environments.
+
+## NodeJs
+1. Run `npm install` to install all the dependencies.
+1. `lib/hp-client-lib.js` is the Hot Pocket client library for NodeJs.
+1. `text-client.js` is the example for json mode.
+1. `file-client.js` is the example for bson mode.
+
+## Browser
+1. Run `npm install` to install all the compilation dependencies.
+1. Run `npm run build-browser` to produced the minified library for the browser.
+1. `browser-example.html` is the simple html/javascript example for json mode.
+
+(For BSON support in browser, a slightly modified version of https://www.npmjs.com/package/bson is used. The minified library includes this bson support library as well)

+         * or change in sign.
+         * In the algorithms below, we frequently reduce the negative case to the
+         * positive case by negating the input(s) and then post-processing the result.
+         * Note that we must ALWAYS check specially whether those values are MIN_VALUE
+         * (-2^63) because -MIN_VALUE == MIN_VALUE (since 2^63 cannot be represented as
