[plt-scheme] standalone exes

Hi there,

I have been playing around with creating standalone exe's (not 
launchers) and I am having a little trouble.


1) I tried to use:

    mzc --exe t.scm

where t.scm is:
  
    (module t mzscheme (display "hello"))

And I get:

mzc: expects <file/directory/collection> 
[<file/directory/sub-collection>] ... on the command line, given 0 arguments

Note that `mzc t.scm' seems to work, a t.dll is created.

 
2) The above works if I set the language level to module in DRScheme and 
select "Create Executable...". But I have been unable to create an .exe 
for a program that uses a native extension. Can this be done or do I 
need to link the native code into the mzscheme .exe myself?

Thanks in advance,
-pp
