This book uses several Ruby gems for the code examples. Things move quickly in the open source world, and the versions of many of the gems we’ve used will have been superseded by the time you read this. You’ll find the code examples will work best if you use the same versions of the gems as we did, so there’s a complete list of them in this appendix.
To install these gems, create a working directory where you’ll be writing the code examples, and download this Gemfile:
