Conventions Used in this Book

The many different kinds of software discussed in this book made it a real struggle to come up with consistent typographical conventions. Here are the rules I’ve tried to follow:

Constant Width

Used for generic, HTML, SQL, and XML code. Also used for message headers.

Constant Width Bold

Used for user input.

Constant Width Italic

Used for replaceable elements, including markers and abstract markers.

Italic

Used for commands, filenames, functions, GUI labels, modules, newgroups, script names, URLs, and URL fragments. Also used to introduce new terms and for emphasis.
