Thanks for moving this thread to vm-dev.

The latter code probably tried to get options to conform to unix 
convention of using single dash for single letter options and double 
dash for word options for all its applications. This convention applies 
to unix apps but need not apply to virtual machines like qemu-* or 
squeak*. Both these VMs use single dash for all their options.

I feel it is fine to stick to single dash for all squeak options but 
have the code accept both single and double dashes as prefixes. Generate 
strictly but accept liberally. All our scripts will use single dash, but 
if someone types in double-dash due to habit, the VM will recover 
gracefully.

Esteban? What do you think?

I can generate a patch to fix this, if there is a general consensus on 
this list.
