A package containing the implementation of the builder for combined
configurations.

 The CombinedConfigurationBuilder class defined in this package can create a CombinedConfiguration object from various configuration sources that are declared in a so-called configuration definition
file. This is a convenient means to collect distributed configuration
information and access them as a single logic source.

 In addition, the MultiFileConfigurationBuilder class is located in this package. This builder class selects one file-based configuration out of a set based on dynamic variable substitution. A typical use case would be the definition of multiple configuration files for the different stages of a project: development, integration test, production, etc.
