Just a placeholder so it won't slip through the TODO list - I have had a couple of people asking for this feature lately, so that's something to look into after we merge a good part of the issues on the tracker :)
Is there some documentation on this somewhere? If it's short, feel free to stick it in a comment in this bug. :-)
I've read these two links in the past, they seem okay.
I think barring the many different types in the format, the only real engineering we need to do inside rmac is to finally support named sections (ie. other than the hardcoded text/data/bss/etc). After that I think it should be relatively straightforward.
