         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.
