I, too, am still a little unclear  regarding how the new style staging
works. Are you saying that we are able now to simply remove the do_stage()
function and bitbake will somehow just know which files are intended to be
staged from the install.. what if a [say header] file that was not
previously "installed" is required by a dependent recipe?

further, if Franz simply builds just one recipe (say "B") that depends on
another recipe ("A"), B might not make use of all the files staged by A,
whereas a 3 recipe may use some other files... so that method of testing is
not sufficient.... I *think* that is what Koen was saying in his most recent
reply.. right?

Still, is there some documentation on exactly how you are supposed to do the
"new-style" staging and how it works...

thanks mike
