Config file formatting
Lines starting with # will be read as the option description.
Blank lines will terminate the current option or description.
The syntax for setting an option is Key=Value.
An empty key will result in a null value where the option type is nullable, otherwise, it will use the default value.
To force an option to use its default setting, prefix it with an @, ex:
@Key=Value
This will ignore the current value setting and suppress config warnings about options using their default values.
