The sfAdvancedConstPlugin is a symfony plugin that provides app wide constants functionality. It automatically generates constant values based on sfRefTable values and make them accessible in every app module. It works the following way - go through the tables defined in sfRefTable and generate for each id / name pair from this table constants. This plugin is different from sfConst plugin which required to keep all the constants directly in sfConst table and did not require ref tables. Effectively, both plugins are usefull to be used.
