+ * FreeRTOS+FAT FS V1.0.0 (C) 2013 HCC Embedded
+ *
+ * The FreeRTOS+FAT SL license terms are different to the FreeRTOS license 
+ * terms.
+ * 
+ * FreeRTOS+FAT SL uses a dual license model that allows the software to be used
+ * under a pure GPL open source license (as opposed to the modified GPL licence
+ * under which FreeRTOS is distributed) or a commercial license.  Details of 
+ * both license options follow:
+ * 
+ * - Open source licensing -
+ * FreeRTOS+FAT SL is a free download and may be used, modified, evaluated and
+ * distributed without charge provided the user adheres to version two of the 
+ * GNU General Public License (GPL) and does not remove the copyright notice or 
+ * this text.  The GPL V2 text is available on the gnu.org web site, and on the
+ * following URL: http://www.FreeRTOS.org/gpl-2.0.txt.
+ * 
+ * - Commercial licensing -
+ * Businesses and individuals who for commercial or other reasons cannot comply
+ * with the terms of the GPL V2 license must obtain a commercial license before 
+ * incorporating FreeRTOS+FAT SL into proprietary software for distribution in 
+ * any form.  Commercial licenses can be purchased from 
+ * http://shop.freertos.org/fat_sl and do not require any source files to be 
+ * changed.
+ *
+ * FreeRTOS+FAT SL is distributed in the hope that it will be useful.  You
+ * cannot use FreeRTOS+FAT SL unless you agree that you use the software 'as
+ * is'.  FreeRTOS+FAT SL is provided WITHOUT ANY WARRANTY; without even the
+ * implied warranties of NON-INFRINGEMENT, MERCHANTABILITY or FITNESS FOR A
+ * PARTICULAR PURPOSE. Real Time Engineers Ltd. and HCC Embedded disclaims all
+ * conditions and terms, be they implied, expressed, or statutory.
