+ * Baculum asset manager.
+ * This additional asset manager layer is required to avoid issue with updating
+ * asset directory. It bases on two framework methods responsible for copying
+ * files and directories which instead of checking if:
+ *
+ *   asset file MTIME < original file MTIME
+ *
+ * here do copying assets everytime if:
+ *
+ *   asset file MTIME != original file MTIME
+ *
+ * This behavior is specially useful for upgrades when can be case for which:
+ *
+ *   asset file MTIME > original file MTIME
+ *
+ * and in real the original file MTIME has newer content than that one in
+ * asset directory. It is because copy() changes MTIME of destination file.
