+ * 
+ * PHP-Scoper also can not handle Composers static file autoloaders. 
+ * This is due to Composer loading files based on a hash which is generated from package name and relative file path. 
+ * For a workaround see #298. https://github.com/humbug/php-scoper/blob/master/docs/limitations.md#composer-autoloader
+ * 
+ * Script taken from https://github.com/humbug/php-scoper/issues/298#issuecomment-525700081
+ * 
+ * This helper is needed to "trick" composer autoloader to load the prefixed files
+ * Otherwise if a dependency contains the same libraries ( i.e. guzzle ) it won't
+ * load the files, as the file hash is the same and thus composer would think this was already loaded
+ *
+ * More information also found here: https://github.com/humbug/php-scoper/issues/298
