+Delete VPGs by VM list (CSV)
+
+This script reads a CSV file with a required "VMName" column (case-insensitive),
+validates each VM using the VMs.list_vms API, and deletes the VPG associated
+with each VM using VPGs.delete_vpg.
+
+Required Arguments:
+    --zvm_address: ZVM address
+    --client_id: Keycloak client ID
+    --client_secret: Keycloak client secret
+    --csv_file: Path to CSV file containing VMName column
+
+Optional Arguments:
+    --ignore_ssl: Ignore SSL certificate verification
+
+Example Usage:
+    python delete_vpgs_from_csv.py \
+        --zvm_address "192.168.111.20" \
+        --client_id "zerto-api" \
+        --client_secret "your-secret-here" \
+        --csv_file "vm_list.csv" \
+        --ignore_ssl
