From the README: "MochiWeb is an Erlang library for building lightweight HTTP servers." This book contains the MochiWeb source code. This is a small book, formatted to toss around at 5.5"x8.5". Line numbers were added, as well as light source code highlighting (mostly bolding and fonts differences). A table of contents is at the end of the book. I made this book because I can't read, mark-up, or highlight materials nearly as well on a screen as I can on paper. This is a cheap learning aid for a great project.
