		/**
	 * Maven defines contributors and developers in the POM. This annotation will
	 * generate a (not standardized by OSGi) Bundle-Contributors header.
	 * <p>
	 * This annotation can be used directly on a type or it can 'color' an
	 * annotation. This coloring allows custom annotations that define a specific
	 * contributor. For example:
	 * 
	 * <pre>
	 *   {@code @}BundleContributor("Peter.Kriens@aQute.biz")
	 *   {@code @}interface pkriens {}
	 *   
	 *   {@code @}pkriens
	 *   public class MyFoo {
	 *     ...
	 *   }
	 * </pre>
	 * 
	 * Duplicates are removed before the header is generated and the coloring does
	 * not create an entry in the header, only an annotation on an actual type is
	 * counted. This makes it possible to make a library of contributors without
	 * then adding them all to the header.
	 * <p>
	 * See <a href=https://maven.apache.org/pom.html#Developers>Maven POM reference</a>
