+Do we have any open openssl PR requests that have the label
+"approval: done" that are over 24 hours old?  If so if there
+have been no other comments added since then we can automatically
+move them to "approval: ready to merge"
+
+You need a token to make label changes and to ensure you don't
+hit rate limiting if you just want a dry run.  Get one from
+https://github.com/settings/tokens/new select 'repo' only
+then put it in token.txt (prefix with the string "token ", i.e.
+echo "token 12903413aaaaaa" > token.txt
+
+to see what it would do:
+
+python github-approve-label-workflow --debug --token token.txt
+
+or to also actually change any labels
+
+python github-approve-label-workflow --debug --token token.txt --commit
