Cool... I think, if I check today, that the only difference between my
sandbox and the official repository is that I still haven't gotten around to
submitting my OMAP port.

I am assuming that I need to send in the copyright assignment form before
the port will be accepted.  Is that still true?  Regardless, I haven't put
any Delphi (or, for that matter, my own) copyrights in the code.  Just
laziness on my part.  So the code all has the standard eCos copyrights
(which, says it's all copyrighted by RedHat).
