+# These packages still require Python 3.6.  They are either dead
+# upstream or their maintainers are simply unresponsive.
+# Please do not remove any packages from this list unless you actually
+# port them to Python 3.7 *and* 3.8 (3.9 would also be nice).
+# Removal in 30 days.  Tracker bug #695996.
