    Contains Guava's com.google.common.util.concurrent.ListenableFuture class,
    without any of its other classes -- but is also available in a second
    "version" that omits the class to avoid conflicts with the copy in Guava
    itself. The idea is:

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