github permissions for parrot. Could the resigned admins please
handover the perms?

+=head1 SMOKE TESTS
+
+Parrot uses several smoker services.
+
+Our own C<make smoke> test results are at
+L<http://smolder.parrot.org/app/projects/smoke_reports/1>.
+
+All C<smoke-me/> and C<master> branch changes are automatically smoked
+on linux and darwin at L<https://ci.appveyor.com/project/rurban/parrot/>.
+
+You can trigger manual win32 and win64 smokes with MSVC 10 and 12 for the
+C<smoke-me/appveyor> branch at L<https://ci.appveyor.com/project/rurban/parrot/>.
