+# Helper script for sending command scripts to Steward.
+# Uses a template.yaml file and fils in the shell variables
+# specified within the template.
+# If no template file exist a default template.yaml file
+# will be created.
+# The template.yaml file can be modified to suit your own
+# needs
+#
+# Example:
+# ./clifoldertemplate.sh myship1,myship2 /bin/bash 'ls -l /etc'
+#
+# The scripts takes three arguments:
+# First: A single node name, or a comma separated list of more node names.
+# Seconds: The path to the interpreter as seen on the node the message is sent to.
+# Third: The actual command execute specified within single quotes.
+
+# Create template is used when no template file is found,
+# and will create a default template.yaml file.
