11 | * mapfix_default_size (by default 24) : size used when omitted
12 | * mapfix_max_size (by default 32) : maximum size allowed for players
13 | * mapfix_delay (by default 15) : minimal delay in seconds between 2 `/mapfix` (to avoid server freezing)
14 | * mapfix_priv (by default server) : priv that allows use of `/mapfix` without restrictions
