All sounds good to me, though I will quickly point out again that the
above example at least could be:

push( @includes, qw(

  %P/chips/stm25p
  %P/chips/cc2420

  %T/chips/cc2420
  %T/chips/cc2420/alarm
  %T/chips/cc2420/control
  %T/chips/cc2420/csma
  %T/chips/cc2420/interfaces
  ...
  ...

as %P is replaced by the directory of the .platform file... Note that
this does assume you're eventually invoking ncc something like this:
  ncc -I$TOSCONTRIB/ecosens1 -target=ecosens1 <other options and files>
