Simply pass the arguments after the image-name, that should work with
the Unix and the Mac VM. By default the image will try to file-in the
first argument (it assumes it is a script), so you probably need to
change that (somewhere in a start-up method) an put your own parse
code in there. The code "SmalltalkImage current extractParameters"
answers a collection of command line parameters.

As far as I know this only works on the Unix VM with OS Process.

Once I wrote a plugin for Squeak to directly access the Posix
filesystem functions on Unix, because of the bugs with file-access in
Squeak. This also allowed to read and write to stdout, stdin and
stderr by performing the primitives on the file-handles 0, 1 and 2
respectively. I can show you that code if you like.
