Everything curl is an extensive guide to everything there is to know about curl, the project, the command-line tool, the library, how everything started and how it came to be what it is today. How we work on developing it further, what it takes to use it, how you can contribute with code and bug reports and why all those millions of existing users use it. This book is meant to be interesting and useful to both casual readers and the somewhat more experienced developers, and offers something for you all to pick and choose from. Don't read it from front to back. Read the chapters you are curious about and go back and forth as you see fit.
