Each parameter is declared the following way : **{name, ptype, default_value, description}**. The output will be registered in the system automatically.
- +
-After creating your output you need to register it. This is achieved by calling **output.register(my_output)**. When loading the lua script, the function **<filename>_register()** will be called. This means that if you save your output in the file **my_output.lua**, the function **my_output_register()** will be called when loading the lua script to register the output with the system.+
