I read the AWDWR,And I writing note about rails and ruby for myself.I really like the layout of this book. Q: 1 Which compose software are u using? 2 Would you open stylesheet file for reader? 3 How do you render the ruby source in the book? thanks!
I use vim, Dave uses Emacs.
I believe that’s custom and proprietary. you might want to direct that question to Pragmatic Programmer’s directly.
