+"""Lie qualys_assets a servers via IP quand le hostname ne match pas.
+
+Cas d'usage : Qualys enregistre l'asset sous un display name (ex 'node3') alors
+que le vrai serveur dans iTop/PatchCenter s'appelle differemment (ex 'vdameasxt3').
+On retombe sur le matching par IP via server_ips.
+
+Ne touche QUE les qualys_assets dont server_id est NULL.
+
+Usage:
+    python tools/link_qualys_by_ip.py [--dry-run]
