Indeed :-) The thing is that, at the end of the day, the common
denominator for almost everything is a Makefile. So that seems to be
a good point to make that switch in a way that's transparent to most
of the developers.

No matter how great OE is, the less I need to worry about it when I
only need its services, but don't intend to change its shape, the

That's probably a good approach. I was thinking more in terms of
documentation, but "executable documentation" is great to have for
many reasons.

I think insisting on replacing the build scripts of the code I'm
working on would already be one step too aggressive. If a package
cross-compiles without a fight, or if it's easy to adjust, the
cross-build environment shouldn't try to impose its own style.

I haven't noticed our meta-toolchain-derived toolchain doing anything
like this, so the direction looks good to me so far.

Indeed it does. Thanks ! ;-)
