Mercurial

Mercurial is a version control system that tracks changes to files over time, allowing multiple people to collaborate on projects efficiently. It records every modification, so you can view, revert, or compare different versions of files easily. Think of it as a detailed history book for your project, making it simple to manage revisions, experiment safely, and maintain consistency across contributors. Used mainly in software development, Mercurial helps teams coordinate work, prevent conflicts, and ensure the integrity of their project’s progress.
