Mercurial
Mercurial is a system that helps software developers track changes in their code over time. It's like a highly organized digital filing cabinet that remembers every change made to software projects. Developers use Mercurial to save different versions of their work, collaborate with others, and safely experiment with new features without risking the main project. It's similar to other version control systems like Git or Subversion. When you see Mercurial (sometimes called "Hg") mentioned in a resume, it shows that the candidate has experience working with professional code management tools, which is important for team-based software development.
