CVS, short for Concurrent Versions System, is a version control system used for tracking changes in source code files during software development. It allows multiple developers to collaborate on a project simultaneously, managing concurrent edits and ensuring that changes are merged seamlessly.
With CVS, developers can check out files from a central repository, make modifications, and then commit their changes back to the repository. CVS keeps track of different versions of files, allowing developers to revert to previous versions if needed and compare changes between versions.
While CVS was once a popular choice for version control, it has largely been superseded by newer systems such as Git, which offer more advanced features and better performance. However, CVS still has some legacy use cases and may be found in older software projects.
