+usage="kubectl $(basename "$0") [-h] NAMESPACE NAME
+kubectl plugin, requires TILLER_NS set before call. Will run helm delete --purge on release associated with pod.
+Release is acquired from the pod's 'describe' information in the 'tags' section.
+Examples:
+  kubectl purge my-namespace my-namespace-pod1-123: Purge the release associated with 'my-namespace-pod1-123' pod"
+while getopts ':h' option; do
+  case "$option" in
+    h) echo "$usage"
+       exit
+       ;;
+  esac
+done
