text: Comparison of version-control software
User interfaces
Table explanation Software : The name of the application that is described . Web Interface : Describes whether the software application contains a web interface . A web interface could allow the software to post diagnostics data to a website , or could even allow remote control of the software application . GUIs : A GUI is a graphical user interface . If a software product features a GUI its functionality can be accessed through application windows as opposed to accessing functionality based upon typing commands at the command prompt such as a DOS interface . Plug-ins : functionality is available through an Integrated Development Environment . Minimum functionality should be to list the revision state of a file and check in/check out files .
The following is a comparison of version-control software. The following tables include general and technical information on notable version control and software configuration management (SCM) software. For SCM software not suitable for source code, see Comparison of open-source configuration-management software.
