/**
 * The provisional interfaces defining the various sub components that implement the repository system. Aether Core
 * provides stock implementations for most of these components but not all. To obtain a complete/runnable repository
 * system, the application needs to provide implementations of the following component contracts:
 * {@link org.eclipse.aether.impl.ArtifactDescriptorReader}, {@link org.eclipse.aether.impl.VersionResolver},
 * {@link org.eclipse.aether.impl.VersionRangeResolver} and potentially
 * {@link org.eclipse.aether.impl.MetadataGeneratorFactory}. Said components basically define the file format of the
 * metadata that is used to reason about an artifact's dependencies and available versions.
