This book is written for computer-literate folk who want to use Subversion to manage their data. While
Subversion runs on a number of different operating systems, its primary user interface is command-line
based. It is that command-line tool (svn) which is discussed and used in this book. For consistency, the
examples in this book assume the reader is using a Unix-like operating system, and is relatively comfort-
able with Unix and command-line interfaces.
