Full List of EE Config Overrides
A new addition to the EE documentation is this full list of System Configuration Overrides. The overrides–in the past documented in the wiki and other places–allow you to override default values or values set through the control panel and saved in the database right in your config file. This is handy if you need those values to differ between environments (local, dev, production).
