This is ported from django.conf Settings and configuration for Tic.
Values will be read from the module specified by the TIC_SETTINGS_MODULE environment variable, and then from tic.conf.global_settings; see the global settings file for a list of all possible variables.
Bases: tic.utils.functional.LazyObject
A lazy proxy for either global Django settings or a custom settings object. The user can manually configure settings prior to using them. Otherwise, Django uses the settings module pointed to by DJANGO_SETTINGS_MODULE.
Called to manually configure the settings. The ‘default_settings’ parameter sets where to retrieve any unspecified values from (its argument must support attribute access (__getattr__)).
