	# This workflow doesn't do anything, it's only use is to trigger "workflow_run"
	# webhook, that'll be consumed by gitspiegel
	# This way, gitspiegel won't do mirroring, unless this workflow runs,
	# and running the workflow is protected by GitHub

	pull_request:
	types:
	- opened
	- synchronize
	- unlocked
	- ready_for_review
	- reopened
	# doesn't work as intended, triggers "workflow_run" webhook in any case
	# the job doesn't check out any code, so it is relatively safe to run it on any event
