181 There, you can find all of the code appearing in this book, with prose interspersed in comments, in exactly the order that you find in this document. You can step through the code interactively with your chosen graphical Coq interface. The code also has special comments indicating which parts of the chapters make suitable starting points for interactive class sessions, where the class works together to construct the programs and proofs. The included Makefile has a target %\texttt{%#<tt>#templates#</tt>#%}% for building a fresh set of class template files automatically from the book source. 181 There, you can find all of the code appearing in this book, with prose interspersed in comments, in exactly the order that you find in this document.

183 I believe that a good graphical interface to Coq is crucial for using it productively. I use the %Proof General\footnote{\url{http://proofgeneral.inf.ed.ac.uk/}}%#<a href="http://proofgeneral.inf.ed.ac.uk/">Proof General</a># mode for Emacs, which supports a number of other proof assistants besides Coq. There is also the standalone CoqIDE program developed by the Coq team. I like being able to combine certified programming and proving with other kinds of work inside the same full-featured editor, and CoqIDE has had a good number of crashes and other annoying bugs in recent history, though I hear that it is improving. In the initial part of this book, I will reference Proof General procedures explicitly, in introducing how to use Coq, but most of the book will be interface-agnostic, so feel free to use CoqIDE if you prefer it. 183 I believe that a good graphical interface to Coq is crucial for using it productively.

The one issue with CoqIDE, regarding running through the book source, is that I will sometimes begin a proof attempt but cancel it with the Coq [Abort] command, which CoqIDE does not support. It would be bad form to leave [Abort] commands lying around in a real, finished development, but I find these commands helpful in writing single source files that trace a user's thought process in designing a proof.

185 The next chapter will introduce Coq with some simple examples, and the chapter starts with step-by-step instructions on getting set up to run the book chapters interactively, assuming that you have Coq and Proof General installed.
