Indead, I failed miserably on that (describing the problem intended to be solved).
The general sense is to unify the argument parsing strategies with some benefits
like help generation. If you see, every qemu binary has its own strategy - where
some (most?) use getopt and the QEMU main binary uses QemuOpt, they lack a runtine
help message generation, the sync between the help message and expected/implemented
arguments are done manually.

But I'm not sure if we really want/need it, that's the why I sent an early RFC. For
me it was just few weekend hours putting all together. :)

I see a good benefit on that - having a simple, clean, consistent and common API
throughout the source code. But again, do we want it? is it worth it?

Regards...
