Book
Agile publishing for agile developers
The book you’re reading is still under development. As part of our
Beta book program, we’re releasing this copy well before we normally
would. That way you’ll be able to get this content a couple of months
before it’s available in finished form, and we’ll get feedback to make
the book even better. The idea is that everyone wins!
Be warned. The book has not had a full technical edit, so it will con-
tain errors. It has not been copyedited, so it will be full of typos and
other weirdness. And there’s been no effort spent doing layout, so
you’ll find bad page breaks, over-long lines with little black rectan-
gles, incorrect hyphenations, and all the other ugly things that you
wouldn’t expect to see in a finished book. We can’t be held liable if you
use this book to try to create a spiffy application and you somehow
end up with a strangely shaped farm implement instead. Despite all
this, we think you’ll enjoy it!
Throughout this process you’ll be able to download updated PDFs
from your account on
http://pragprog.com. When the book is finally
ready, you’ll get the final version (and subsequent updates) from the
same address. In the meantime, we’d appreciate you sending us your
feedback on this book at
http://pragprog.com/titles/achbd/errata, or by
using the links at the bottom of each page.
Thank you for being part of the Pragmatic community!
