+ NAME
+ check-blueprint-vs-input - given a blueprint and inputs file pair, validate them against each other
+
+ USAGE
+ check-blueprint-vs-input [-v] [-t] -b BLUEPRINT [-B exclusion-list] -i INPUTS [-B exclusion-list]
+
+ DESCRIPTION
+"""
+description = """
+ Validate a blueprint and inputs file against each other. This looks for the inputs: node of the blueprint
+ file, the inputs used by {get_input} within the blueprint, and the values found in the inputs file. The
+ files may be in either YAML or JSON formats. The names default to blueprint.yaml and inputs.yaml. If
+ a blueprint inputs name has a default value, it is not considered an error if it is not in the inputs file.
+
+ If using a template inputs file, add the -t/--template option. This will look for the inputs under
+ an "inputs:" node instead of at the top level.
+
+ If there are blueprint nodes or inputs nodes that should not be considered an error, specify them
+ using the -B/--blueprint-exclusion-list and -I/inputs-exclusion-list parameters.
+
+ "check-blueprint-vs-input --help" will list all of the available options.
