*** FREERTOS+TCP IS STILL IN THE LAB (mainly because the FTP and HTTP ***
*** demos have a dependency on FreeRTOS+FAT, which is only in the Labs ***
*** download): ***
*** ***
*** FreeRTOS+TCP is functional and has been used in commercial products ***
*** for some time. Be aware however that we are still refining its ***
*** design, the source code does not yet quite conform to the strict ***
*** coding and style standards mandated by Real Time Engineers ltd., and ***
*** the documentation and testing is not necessarily complete. ***
*** ***
*** PLEASE REPORT EXPERIENCES USING THE SUPPORT RESOURCES FOUND ON THE ***
*** URL: http://www.FreeRTOS.org/contact Active early adopters may, at ***
*** the sole discretion of Real Time Engineers Ltd., be offered versions ***
*** under a license other than that described below. ***

*
* FreeRTOS+TCP can be used under two different free open source licenses. The
* license that applies is dependent on the processor on which FreeRTOS+TCP is
* executed, as follows:
*
* If FreeRTOS+TCP is executed on one of the processors listed under the Special
* License Arrangements heading of the FreeRTOS+TCP license information web
* page, then it can be used under the terms of the FreeRTOS Open Source
* License. If FreeRTOS+TCP is used on any other processor, then it can be used
* under the terms of the GNU General Public License V2. Links to the relevant
* licenses follow:
