Conventions Used in This Tutorial

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

    Italic
  • Used to indicate new terms, URLs, filenames, file extensions, directories, commands and options, program names, and to highlight comments in examples. For example, a path in the filesystem will appear as /Developer/Applications.
    Constant width
  • Used to show code examples, verbatim Google searches, the contents of files, or the output from commands. 
  • Constant width bold
  • Used in examples and tables to show commands or other text that should be typed literally.
    Constant width italic
  • Used in examples and tables to show text that should be replaced with user-supplied values.
    Color

    You should pay special attention to notes set apart from the text with the following icons:
