In my case, the library is written in C and I make bindings for it.  So
this is closer to the first model, like Gnu Makefile.  But it is not
meant for users scripting, but developers scripting.

I always have this shebang now in my Guile scripts (might not work on
fedora because the guile binary is guile3):

#!/bin/sh
#-*-Scheme-*-
exec guile --no-auto-compile -e main -s "$0" "$@"
!#
