  <version>1.0</version>
  <name>Guava ListenableFuture only</name>
  <description>
    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.

  <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.
