Top posting because I can't contribute anything meaningful inline...
Wow, Albert, this looks very, very cool. I have heard of using 'make'
and creating your own make files to do things like this, but after a few
minutes of perusing these files I realize this is just way over my head,
at least without some kind of tutorial (I'm just a lowly user whose
(lack of) bash skills would make most of you guys laugh).
Do you know of any generic tutorials on using creating/using your own
make files to do repetitive tasks (not necessarily like building an
entire system as you are doing here (but if there is something like that
If not, no worries.
Anyway, thanks for sharing what you've done here...
