The manual way of provisioning Carbon is by dropping bundles and configuration files that belong to a feature. This method is not recommended since it can cause errors. Besides, finding the exact set of components and configuring files is a complex task. Components have inter-dependencies with other components. Some components depend on specific versions of other components.
The WSO2 Feature Repository consists of features that are bundled into WSO2 products that are based on a particular Carbon release. The feature repository for WSO2 products based on Carbon 4.4.x versions is http://product-dist.wso2.com/p2/carbon/releases/wilkes/.
