+# This script can be used for generating chargeback data for vmware in SPP

+# The script provides output to screen or destination file in csv
+# Example:
+#    python3 vmware_chargeback2.py --host="https://172.20.49.50" --user="admin" --pass="password123"
+#    python3 vmware_chargeback2.py --host="https://172.20.49.50" --user="admin" --pass="password123" --dest="output.csv"
