如何使用sugarcrm中的Module Loader在config_override.php中添加自定义代码？

I just want to add some additional configuration code in config_override.php in SugarCRM. Is it possible to write in manifest.php file and append it through module loader. When I am adding using copy array in $installdefs in manifest file then sugar is replacing my file with config_override.php file.

$installdefs = array(
              'copy' => array(  
                   0 => array(
                'from' => '<basepath>/moduleName/myconfg.php',
                'to' => 'config_override.php',
            ), ), );

I just want to append in config_override.php not replace whole file . Any help will be appreciated .

In your install package in /scripts/post_install.php:

function post_install() {
    require_once('modules/Configurator/Configurator.php');
    $cfg = new Configurator();

    /** Your setting to save in config_override.php */
    $cfg->config['myaddon_setting'] = true;
    $cfg->handleOverride();  
}
