Chapter 4. Tagging and Branching

One of the most helpfulyet underusedfacilities of CVS is the tag. CVS's tagging feature allows you to label a revision for later retrieval. This feature also allows you to fork development so that you can work on two or more lines of development of your project simultaneously. The line that has been forked off is called a branch, and the original line is called the trunk.

If your project has never been branched, the project is on the trunk.

This chapter explains tags, branches, and how to merge branches and trunks. It also discusses why and when to branch and provides strategies and hints for using branches effectively in your project.
