<name>Guava ListenableFuture only</name>
  <description>
    An empty artifact that Guava depends on to signal that it is providing
    ListenableFuture -- but is also available in a second "version" that
    contains com.google.common.util.concurrent.ListenableFuture class, without
    any other Guava classes. The idea is:

    - If users want only ListenableFuture, they depend on listenablefuture-1.0.
