+       <em>Pragmatic Project Automation</em> shows you how to improve the

+       automation to reduce risk and errors.

+        for you doing the mundane (but important) project stuff. That means
+        you'll have more time and energy to do the really
+        exciting---and difficult---stuff, like writing quality code.

+         This book is a recipe-based approach to using Subversion that will
+         get you up and running quickly---and correctly. All projects need
+         version control: it's a foundational piece of any project's
+         infrastructure. Yet half of all project teams in the U.S. don't use
+         any version control at all. Many others don't use it well, and end
+         up experiencing time-consuming problems.

+    %{<p>
+        Pragmatic programmers use feedback to drive their development and
+        personal processes. The most valuable feedback you can get while
+        coding comes from unit testing.
+      </p>
+      <p>
+        Without good tests in place, coding can become a frustrating game of
+        "whack-a-mole." That's the carnival game where the player strikes at a
+        mechanical mole; it retreats and another mole pops up on the opposite side
+        of the field. The moles pop up and down so fast that you end up flailing
+        your mallet helplessly as the moles continue to pop up where you least
+        expect them.
