IMHO, the best way would be to support SRFI-22 (Running Scheme scripts
in Unix, http://srfi.schemers.org/srfi-22/srfi-22.html), which calls a
procedure named main in the body of a script starting with

#!/usr/bin/env guile

after evaluating the body, passing to it as arguments the provided
command line ones [1]. Besides being a simple approach, it would be make
live easier for people writing code intended for multiple schemes.

Footnotes: 
[1]  Actually, i'm oversimplifying here: the SRFI suggests also
concrete names for the interpreter (instead of just 'guile'),
according to its compliance to RnRS.
