-# 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
-         * a positive number, it overflows back into a negative).  Not handling this
-         * case would often result in infinite recursion.
