+ *** FreeRTOS+TCP is functional and has been used in commercial products ***\r
+ *** for some time. Be aware however that we are still refining its ***\r
+ *** design, the source code does not yet quite conform to the strict ***\r
+ *** coding and style standards mandated by Real Time Engineers ltd., and ***\r
+ *** the documentation and testing is not necessarily complete. ***\r
+ *** ***\r
+ *** PLEASE REPORT EXPERIENCES USING THE SUPPORT RESOURCES FOUND ON THE ***\r
+ *** URL: http://www.FreeRTOS.org/contact Active early adopters may, at ***\r
+ *** the sole discretion of Real Time Engineers Ltd., be offered versions ***\r
