+# Examples:
+# RUNNER_CFG_PAT=<yourPAT> ./create-latest-svc.sh myuser/myrepo
+# RUNNER_CFG_PAT=<yourPAT> ./create-latest-svc.sh myorg
+#
+# Usage:
+#     export RUNNER_CFG_PAT=<yourPAT>
+#     ./create-latest-svc scope [name] [user]

+#      scope required  repo (:owner/:repo) or org (:organization)

+#      user  optional  user svc will run as. defaults to current
+# 
+# Notes:
+# PATS over envvars are more secure
+# Should be used on VMs and not containers
+# Works on OSX and Linux 
+# Assumes x64 arch
