com.google.gwt.core.ext.linker.EmittedArtifact
An artifact that will be emitted into the output. All EmittedArtifacts contained in the {@link ArtifactSet} at the end of the Linking process willbe emitted by the compiler into the module's output directory. This type may be extended by Linker providers to provide alternative implementations of {@link #getContents(TreeLogger)}. TODO(bobv): provide a timestamp so we can make the time on output files match that of input files?
