Oro Config Component provides additional resource types to Symfony Config Component infrastructure responsibles for loading configurations from different data sources and optionally monitoring these data sources for changes.

• Cumulative Resources provides a way to configure a bundle from other bundles.

• Configuration Merger provides a way to merge configurations of some resource both from one or many bundles. Supports two strategies: replace and append.

The System Aware Resolver allows to make your configuration files more dynamic. For example you can call service's methods, static methods, constants, context variables etc.
