/**
 * Yii bootstrap file.
 *
 * This file is automatically generated using 'build lite' command.
 * It is the result of merging commonly used Yii class files with
 * comments and trace statements removed away.
 *
 * By using this file instead of yii.php, an Yii application may
 * improve performance due to the reduction of PHP parsing time.
 * The performance improvement is especially obvious when PHP APC extension
 * is enabled.
 *
 * DO NOT modify this file manually.
