define ('T3_LOCAL_DISABLED', 1);

hello, my question refers to the configuration.php file and the following entry: define ('T3_LOCAL_DISABLED', 1);

How to disable the feature?
For developer, template provider, develop a template When, They Do not use the "local" folder, everything is included in template. In this case, disable the new feature They Can by adding the code after} in the last line of the configuration.php.
1. define ('T3_LOCAL_DISABLED', 1);


What is meant by the file „configuration.php“, this I can not find.
Which is then the last } in the "line of the „configuration.php"
For your efforts thanks in advance.
