Standard License Terms

FreeRTOS+CLI (C) 2013 Real Time Engineers ltd.

The FreeRTOS+CLI license terms are different to the FreeRTOS license terms.

FreeRTOS+CLI 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+CLI is
also distributed under the same GPL V2 license terms.  Details of both license
options follow:

- Open source licensing -
FreeRTOS+CLI 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 web site, and on the
following URL:

- Commercial licensing -
Businesses and individuals that for commercial or other reasons cannot comply
with the terms of the GPL V2 license must obtain a low cost commercial license
before incorporating FreeRTOS+CLI into proprietary software for distribution in
any form.  Commercial licenses can be purchased from
and do not require any source files to be changed.

FreeRTOS+CLI is distributed in the hope that it will be useful.  You cannot
use FreeRTOS+CLI unless you agree that you use the software 'as is'.
FreeRTOS+CLI is provided WITHOUT ANY WARRANTY; without even the implied
PURPOSE. Real Time Engineers Ltd. disclaims all conditions and terms, be they
implied, expressed, or statutory.
