    <p>Distributed test execution control for <c>Common Test</c>.</p>

    <p>This module exports functions for running <c>Common Test</c> nodes on
      multiple hosts in parallel.</p>

          However, it is also possible to specify a list of specifications to
          be merged into one specification before the tests are executed. Any
          test without a particular node specification is also executed on
          the nodes in <c>InclNodes</c>. Nodes in the <c>ExclNodes</c> list
          are excluded from the test.</p>
