Preface
In an attempt to make this book as standalone as possible,
I’ve provided an appendix that gives you the very basics of
using the command line, including making edits to text files.
Conventions Used in This Book
The following is a list of the typographical conventions used
in this book:
Italic
Used to indicate URLs, filenames, filename extensions,
and directory/folder names. For example, a path in the
filesystem will appear as /Developer/Applications.
Constant width
Used to show code examples, the contents of files, and
console output, as well as the names of variables, com-
mands, and other code excerpts.
Constant-width bold
Used to display commands or text that the user should
type directly.
Constant-width italic
Used in code examples and tables to show sample text to
be replaced with your own values.
You should pay special attention to notes set apart from the
text with the following styles:
TIP
This is a tip, suggestion, or general note. It contains use-
ful supplementary information about the topic at hand.
WARNING
This is a warning or note of caution.
