Book Description

Subversion sets the standard in version control systems. Championed by open-source developers, Subversion is behind some of today’s biggest and most important software, including Apache, FreeBSD, Ruby, and MediaWiki. But more than just a tool for open-source collaboration, Subversion has made a significant impact in the corporate IT world. Most developers will now encounter Subversion source control during their career.

As a developer, you probably have knowledge of more than one source control tool and are expected to fluidly switch between tools depending on where you are working. This book was written to bridge the gap between knowing something about version control in general and knowing about Subversion specifically.

In Pragmatic Guide to Subversion, author Mike Mason drives developers to the features and practices that have made Subversion so successful. Each of the 48 tasks selected for the book is presented as a quick two-pager, with a succinct description on the left side and a quick reference on the right. The book is designed for experienced developers who know how to learn and want to get straight to the tricks and traps they’d otherwise learn by trial and error.

Subversion started life as a command-line tool but graphical clients are now extremely popular and can offer a lot of extra power. For every task in Pragmatic Guide to Subversion, you get to see how to carry out the task via the regular command-line client as well as the TortoiseSVN graphical client for Windows, and the Cornerstone graphical client for Mac.
