Hello Sylvain, This a draft of Documentation/powerpc/bestcomm.txt, it was born since I couldn't find DRD/LCD description and "... graphical task builder are currently in development" (quotation from AN2604) :(, so I try write doco by myself. Here result of my reverse engineering. If you or somebody have more information or found some bugs, please, fix/expand my text, especially places marked by "?". -- Regards Andrey Volkov
