<p>
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. dont use any version
control at all. Many others dont use it
well, and end up experiencing
time-consuming problems.
