Basically what I'm looking for first is a command line equivalent
replacement first for gnu objcopy. I'd focus on ELF first, and then move to
COFF/PE. I'd start from the work that Jake (cc'd) has already done and work
with Zach (cc'd) on the COFF stuff if he's still interested. Of course,
I'll be around for the first bit.

Then follow up with objcopy, etc as there's time.

Showing off your previous work is absolutely great in a proposal. A
timeline and some proof that you've at least looked at what's missing and
have ideas at how to do the work would be key. And I don't really expect
you to finish all of them - at least not without help, but with some luck
there might be other contributors to help :)

Sound good? We can definitely work on the details as you're interested -
I'll also be more responsive in the near future as well.

Thanks!
