+SUMMARY="Backport of the concurrent.futures package from Python 3"
+DESCRIPTION="This is a backport of the concurrent.futures standard library \
+module to Python 2.
+
+It should not be installed on Python 3, although there should be no harm in \
+doing so, as the standard library takes precedence over third party libraries."
