Sounds like a plan.
I wouldn't worry too much about Win9x. Is IPC::Run in perl core?

I'd test it, but I don't have access to any Win9x boxes anymore. IPC::Run
is not a core module, but I think it's worth the dependency. I considered
IPC::Open3, but it can't be made reliable on Win32, something about not
being able to select() on filehandles, only sockets. I also looked at
IPC::Run3, but under the hood, it's just got STDOUT/STDERR redirection
layered on top of system(). I don't like using system() due to issues with
signals (Such as the user hitting ctrl-c and taking out the child). I feel
better knowing the wrapped executable is in another process disconnected
from the console.
Sendu's suggestion (_set_from_args() ) is the best. As mentioned in

I'm using _rearrange() now. I'll look at _set_from_args(). Is either one
preferred to the other?
