+ * FreeRTOS+UDP V1.0.0 (C) 2013 Real Time Engineers ltd.
+ *
+ * This file is part of the FreeRTOS+UDP distribution.  The FreeRTOS+UDP license
+ * terms are different to the FreeRTOS license terms.
+ *
+ * FreeRTOS+UDP uses a dual license model that allows the software to be used
+ * under a standard GPL open source license, or a commercial license.  The
+ * standard GPL license (unlike the modified GPL license under which FreeRTOS
+ * itself is distributed) requires that all software statically linked with
+ * FreeRTOS+UDP is also distributed under the same GPL V2 license terms.
+ * Details of both license options follow:
+ *
+ * - Open source licensing -
+ * FreeRTOS+UDP 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 that for commercial or other reasons cannot comply
+ * with the terms of the GPL V2 license must obtain a commercial license before
+ * incorporating FreeRTOS+UDP into proprietary software for distribution in any
+ * form.  Commercial licenses can be purchased from http://shop.freertos.org/udp
+ * and do not require any source files to be changed.
+ *
+ * FreeRTOS+UDP is distributed in the hope that it will be useful.  You cannot
+ * use FreeRTOS+UDP unless you agree that you use the software 'as is'.
+ * FreeRTOS+UDP is provided WITHOUT ANY WARRANTY; without even the implied
+ * warranties of NON-INFRINGEMENT, MERCHANTABILITY or FITNESS FOR A PARTICULAR
+ * PURPOSE. Real Time Engineers Ltd. disclaims all conditions and terms, be they
+ * implied, expressed, or statutory.
