* **ARCH**: l'identifiant de la machine cible (architecture du processeur).
* **OS**: l'identifiant de la machine cible (environnement d'execution).
* **TIME**: le timestamp de compilation.
* **TYPE**: le type de conteneur, ex: conteneur, méta-conteneur, etc...
* **VER**: la version de l'entête.
* **HL**: la taille de l'entête en **mot de 32 bits**.
* **MDL**: la taille des méta-données en **mot de 32 bits**.
* **RESERVED**: 20 octets réservés.
* **OPTIONS**: des données optionnels.
* **METADATA**: les informations du contenu (see Cupfile).
* **PAYLOAD**: le contenu.

> **NOTE**:
* Si `HL` == `10d` (`000ah`, frame 0 to 9), alors il n'y à pas d'options.
* Si `MDL` == `0d` (`0000h`), alors il n'y à pas de méta-données.
