Thanks Ernest.  That's a start.  It looks like I can do

   echo Y|cacls /E /R user  filename

Now if I can figure out who is the owner (so I don't remove permissions) 
and what the other "users" are, I'm all set.  I suppose I can get the 
owner via DIR /Q filename.

I'd really like to not have to parse the verbose output that cacls and 
dir create.
