# In simple cases, you don't need a config script. 

# With a simple config_panel.toml, you can write in the app settings, in the 
# upstream config file or replace complete files (logo ...) and restart services.

# The config scripts allows you to go further, to handle specific cases 
# (validation of several interdependent fields, specific getter/setter for a value,
# display dynamic informations or choices, pre-loading of config type .cube... ).
