About This eBook
ePUB is an open, industry-standard format for eBooks.
However, support of ePUB and its many features varies across
reading devices and applications. Use your device or app
settings to customize the presentation to your liking. Settings
that you can customize often include font, font size, single or
double column, landscape or portrait mode, and figures that

you can click or tap to enlarge. For additional information
about the settings and features on your reading device or app,
visit the device manufacturer’s Web site.
Many titles include programming code or configuration
examples. To optimize the presentation of these elements,
view the eBook in single-column, landscape mode and adjust
the font size to the smallest setting. In addition to presenting
code and configurations in the reflowable text format, we have
included images of the code that mimic the presentation found
in the print book; therefore, where the reflowable format may
compromise the presentation of the code listing, you will see a
“Click here to view code image” link. Click the link to view the
print-fidelity code image. To return to the previous page
viewed, click the Back button on your device or app.
