#: Subversion (or SVN for short) is a revision control system that is used to track changes to a project's file repository.  SVN tracks changes to the repository made by each project collaborator. SVN tracks changes and can be used to analyze differences and undo changes at a later time if needed.  This allows for greater collaboration and speed , while minimizing (though never completely elimintating) risks  associated with duplication and overwriting each others work.  Project contents need not be limited to source code files.
