xVarConfig is a tool that is intended to make game server CVAR configuration easy by providing server admins a graphical interface for that task. As the syntax for config files can be defined per xVarConfig profile it can also be used for completely different configuration file types. Only the available configuration options are shown to choose from, along with a description and optionally a screenshot to explain what the setting does.
xVarConfig and the related tools are freeware. That means they can be used free of charge. Also it is not planned to ever change this.

If you are a plug-in author or otherwise interested in creating an xVarConfig settings profile you will need the author tool xVarConfigAuthor.
