There isn't any subtlety :-/  It's waiting for someone to put on a
thinking cap and figure out exactly how to generalize it.  The target's
I've looked at haven't had alternate assembly formats.

The user interactioin is also tricky.  If the user sets the assembly
format, should that carry over when the architecture is changed?
