That's a good point. I missed that.

Indeed, this is what I want but for a modified version of a package
defined in a file. I realized I could do it with

guix graph -e '(load "/path/to/file.scm")'

However, it might be nicer to have something like

guix graph -f /path/to/file.scm

similar to

guix build -f /path/to/file.scm

Yes, I remember such a script too. It would be very useful to have. But,
even I am unable to find it. If someone knows where to find that script,
please share a link.
