Chapter 4. Branching and Merging

"君子务本 (It is upon the Trunk that a gentleman works.)"

—Confucius

Branching, tagging, and merging are concepts common to almost all version control systems. If you’re not familiar with these ideas, we provide a good introduction in this chapter. If you are familiar, hopefully you’ll find it interesting to see how Subversion implements them.

Branching is a fundamental part of version control. If you’re going to allow Subversion to manage your data, this is a feature you’ll eventually come to depend on. This chapter assumes that you’re already familiar with Subversion’s basic concepts (see Chapter 1).
