/**
 * Declares the binaries that should be built for a custom {@link org.gradle.platform.base.ComponentSpec} type.
 *
 * The following example demonstrates how to register a binary for a custom component type using a plugin with a
 * {@link org.gradle.platform.base.ComponentBinaries} annotation.
 * Furthermore the plugin registers 'DefaultSampleBinary' as implementation for {@link org.gradle.platform.base.BinarySpec}.
 *
 * <pre class='autoTested'>
 * interface SampleComponent extends VariantComponentSpec {}
 * interface SampleBinary extends BinarySpec {}
 * class DefaultSampleBinary extends BaseBinarySpec implements SampleBinary {}
 *
 * apply plugin: MyCustomBinariesPlugin
 *
 * class MyCustomBinariesPlugin extends RuleSource {
 *     {@literal @}ComponentType
 *     void register(TypeBuilder&lt;SampleBinary&gt; builder) {
 *         builder.defaultImplementation(DefaultSampleBinary)
 *     }
 *
 *     {@literal @}ComponentBinaries
