Running small scripts

I'm trying to make small scripts to be run from a unix shell.

Looking through the manual I found that scheme48 implements srfi-22, but
I'm having troubles shebanging source files. Is it possible? What do I
need to write at the shebang line? Also, how would I ,open structures
from the script, as I guess I wouldn't be able to use ,open from it.

What I am actually doing to make it work is creating an image with
,build and then using a shell script to run the virtual machine with the
image as the -i argument.
