"""Sync generated *.pyl files to //testing/buildbot.
After modifying the starlark and running it to regenerate configs, if
mixins.pyl has been modified, this script should be run to sync it to
//testing/buildbot. The script can be run with the --check flag to
indicate whether a sync needs to be performed.
mixins.pyl needs to be present in //testing/buildbot because the
directory is exported to a separate repo that the angle repo includes as
a dep in order to reuse the mixin definitions.
