-t, --tile-dir tile cache directory (defaults to '/var/lib/mod_tile')
-z, --min-zoom=ZOOM filter input to only render tiles greater or equal to this zoom level (default is 0)
-Z, --max-zoom=ZOOM filter input to only render tiles less than or equal to this zoom level (default is 18)
-d, --delete-from=ZOOM when expiring tiles of ZOOM or higher, delete them instead of re-rendering (default is off)
