CVS (Concurrent Versions System)

CVS (Concurrent Versions System) is a legacy version control system that was the industry standard in the 1990s. It is a centralized system that lacks many of the features modern developers take for granted, such as atomic commits and robust branching. Today, CVS is considered obsolete and is only used for maintaining ancient codebases that have not yet been migrated to modern systems like Git or Subversion. It is not recommended for any new projects and should be avoided unless you are specifically tasked with maintaining a legacy system that relies on it.
