The following is a list of typographical conventions used in this book:

Used to indicate new terms, URLs, filenames, file extensions, directories, commands and options, and program names, and to highlight comments in examples. For example, a path in the filesystem may appear as C:Hacksexamples or /usr/mike/hacks/examples.
-
Constant width Used to show code examples, XML markup, Java package or C# namespace names, or output from commands.
-
Constant width bold Used in examples to show emphasis.
