Csar is named Concern Separation Aspect Registrar because it provides access to some concern (usually cross-cutting) that may configured either globally or locally to some section of the program. Csar acts like a global service locator that provides flexible, transparent local configuration. Like a czar in American politics, Csar governs configuration and access to program concerns...
You can configure Csar concerns manually, as explained below. Csar also provides a mechanism whereby any library that uses Csar can provide a list of concerns to be automatically available by default without any special configuration required by the program. Simply by including the dependency, for example, will cause any call to to return an implementation that looks up resources stored in resource bundles.
