+"""RaveOS frissítés-ellenőrző.
+
+A raveos-core-repo szinkron adatbázisából kiolvassa a RaveOS saját
+csomagjainak legfrissebb verzióját, összeveti a telepített verziókkal,
+és a /var/lib/raveos-updater/status.json fájlba írja az eredményt.
+
+Használat:
+  check.py          # pacman -Sy után ellenőriz (root; a systemd timer hívja)
+  check.py --no-sync  # nem szinkronizál, a meglévő DB-t használja (pacman hook)
