         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.
