# General Public License Version 2.1 plus the following FreeRTOS exception.
# An independent module is a module which is not derived from or based on
# FreeRTOS.
# Clause 1:
# Linking FreeRTOS statically or dynamically with other modules is making a
# combined work based on FreeRTOS. Thus, the terms and conditions of the GNU
# General Public License cover the whole combination.
# As a special exception, the copyright holder of FreeRTOS gives you permission
# to link FreeRTOS with independent modules that communicate with FreeRTOS solely
# through the FreeRTOS API interface, regardless of the license terms of these
# independent modules, and to copy and distribute the resulting combined work
# under terms of your choice, provided that:
# 1. Every copy of the combined work is accompanied by a written statement that
# details to the recipient the version of FreeRTOS used and an offer by yourself
# to provide the FreeRTOS source code (including any modifications you may have
# made) should the recipient request it.
# 2. The combined work is not itself an RTOS, scheduler, kernel or related
# product.
# 3. The independent modules add significant and primary functionality to
# FreeRTOS and do not merely extend the existing functionality already present in
# FreeRTOS.
# Clause 2:
# FreeRTOS may not be used for any competitive or comparative purpose, including
# the publication of any form of run time or compile time metric, without the
# express permission of Real Time Engineers Ltd. (this is the norm within the
# industry and is intended to ensure information accuracy).
