---Mode players are in when they join for the first time.  Possible values: Creative, Survival. CASE SENSITIVE
 
---IMPORTANT: This formspec must be valid.  If you want compatibility with other inventory-changing mods

---NOTE: At the moment, the creative formspec cannot be changed, as it is required to use variables inside the mod.
---You can try to change it, but it probably will not work.  The same is true for a survival inventory with variables,
---such as inventory_plus.  It is still possible to change the SURVIVAL_FORMSPEC variable inside the code to cope
---with this, but it will not be easy.
