I don't understand.  How will 'rename-file' get the location of the
executable?  For example:

(wrap-program "wget" [...])

I guess that it will only work if you invoke 'wrap-program' from the
same directory.

> For the case where there are have several variables you want to set.

Could you provide an example?  The following works without '#:rest':

(display (wrap-program "wget" '(("PATH" ":" =3D ("/nix/.../gawk/bin"))
                                ("CERT_PATH" ":" suffix ("/nix/.../share/ce=
rts"
                                                         "/nix/.../foo/cert=
s")))))

#!/bin/bash
export PATH=3D"/nix/.../gawk/bin"
export CERT_PATH=3D"$CERT_PATH${CERT_PATH:+:}:/nix/.../share/certs:/nix/...=
/foo/certs"
exec ./.wget-real
