+// Helper script designed to send a cohesive Slack notification about the result of a collection of GitHub workflows
+// This is a simpler variant of notify-from-json.go, due to some issues we
+// encountered around the accuracy of the notification: https://github.com/solo-io/solo-projects/issues/5191
+//
+// This works by:
+// 	1. Read in the test summary
+//  2. Send a Slack notification with the contents
+//
+// Example usage:
+// 	 export SLACKBOT_BEARER=${{ secrets.SLACKBOT_BEARER }}
+// 	 export SLACK_CHANNEL=C0314KESVNV
+// 	go run .github/workflows/helpers/notify/slack_test_summary.go ./_test/test_log/go-test-summary
