I’m sorry for the extra round trip…  Last one, I promise!  :-)

This ‘version’ variable is really unneeded, because:

  (package
    (name "foo")
    (version "bar")
    …)

in fact expands to:

  (let ((name "foo") (version "bar") …)
    (make-struct <package> name version …))

This is done precisely so we can refer to field values.

So please remove the ‘version’ variable.  :-)

> +  (package

Add two columns to the indentation.

> +           ;; Remove teensy rebooter flash binaries
> +           (for-each delete-file (find-files "rebootor" "\\.(elf|hex)$"))

This is equivalent to:

  (find-files "." "\\.(elf|hex)")

because ‘find-files’ is recursive.

Also, please write sentences that start with a capital letter and finish
with a period.

Refer to ‘version’ here instead of hard-coding it:

  (snippet
    `(begin   ; <- note the backquote here, aka. “quasiquote”
       …
       (substitute* …
         (string-append "foo" ,version "\n"))))

Please add an explanation and the upstream status to the beginning of
the patch.

Could you send one last version of the patch please?

Thank you, and apologies to taking so long and being so picky!  ;-)
