Revision Control: Subverting Your Code

Abstract

At one point or another in your days as a developer, chances are you’ve mistakenly deleted an important file. It happens. Sometimes the problem is worse than you thought; for instance, you might not even be sure what files you deleted. Or perhaps your brilliant idea for a new feature has horribly broken the code base. Making matters worse, your changes were spread across multiple files, and now it’s unclear how to return to the previous state. Version control can remedy all of these problems by coordinating the life cycle of all files in your project, allowing you to not only recover mistakenly deleted code, but actually revert back to earlier versions.
