Preface If C gives you enough rope to hang yourself, think of Subversion as a sort of rope storage facility. --Brian W. Fitzpatrick In the world of open-source software, the Concurrent Versions System (CVS) has long been the tool of choice for version control. And rightly so. CVS itself is free soft- ware, and its non-restrictive modus operandi and support for networked operation-- which allow dozens of geographically dispersed programmers to share their work-- fit the collaborative nature of the open-source world very well. CVS and its semi-cha- otic development model have become cornerstones of open-source culture. But like many tools, CVS is starting to show its age. Subversion is a relatively new version control system designed to be the successor to CVS. The designers set out to win the hearts of CVS users in two ways: by creating an open-source system with a design (and look and feel) similar to CVS, and by attempting to fix most of CVS's noticeable flaws. While the result isn't necessarily the next great evolution in version control design, Subversion is very powerful, very usable, and very flexible. This book is written to document the version 1.0 series of the Subversion version control system. We have made every attempt to be thorough in our coverage. How- ever, Subversion has a thriving and energetic development community, so there are already a number of features and improvements planned for future versions of Sub- version that may change some of the commands and specific notes in this book. Audience This book is written for computer-literate folk who want to use Subversion to man- age 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.
