+# Here is a script to deploy cert to hashicorp consul using curl
+# (https://www.consul.io/)
+#
+# it requires following environment variables:
+#
+# CONSUL_PREFIX - this contains the prefix path in consul
+# CONSUL_HTTP_ADDR - consul requires this to find your consul server
+#
+# additionally, you need to ensure that CONSUL_HTTP_TOKEN is available
+# to access the consul server
+
+#returns 0 means success, otherwise error.
