+# Here is a script to deploy cert to hashicorp vault
+# (https://www.vaultproject.io/)
+# 
+# it requires the vault binary to be available in PATH, and the following
+# environment variables:
+# 
+# VAULT_PREFIX - this contains the prefix path in vault
+# VAULT_ADDR - vault requires this to find your vault server
+#
+# additionally, you need to ensure that VAULT_TOKEN is avialable or
+# `vault auth` has applied the appropriate authorization for the vault binary
+# to access the vault server
+
+#returns 0 means success, otherwise error.
