| 1 system.api.php | hook_modules_uninstalled($modules) | 
Perform necessary actions after modules are uninstalled.
This function differs from hook_uninstall() in that it gives all other modules a chance to perform actions when a module is uninstalled, whereas hook_uninstall() is only called on the module actually being uninstalled.
It is recommended that you implement this hook if your module stores data that may have been set by other modules.
Parameters
$modules: An array of the modules that were uninstalled.
