\r
8 * FreeRTOS+UDP uses a dual license model that allows the software to be used
\r
9 * under a standard GPL open source license, or a commercial license. The
\r
10 * standard GPL license (unlike the modified GPL license under which FreeRTOS

\r
22 * - Commercial licensing -
\r
23 * Businesses and individuals that for commercial or other reasons cannot comply
\r
24 * with the terms of the GPL V2 license must obtain a commercial license before
\r
25 * incorporating FreeRTOS+UDP into proprietary software for distribution in any
\r
26 * form. Commercial licenses can be purchased from http://shop.freertos.org/udp
\r
27 * and do not require any source files to be changed.
