(Plan Zero) Write a little shell script that (a) downloads the

I'm happy to apply GPL to the script described above. My reading of
GPL is that a stand-alone general-purpose tool like my Munger need not
be GPL'd merely because it touches the grep executable. (I might apply
a GNU license such as Affero to the Munger tool anyway; I haven't
decided yet.)
I'd also be happy to arrange for the patch applied in step (c) above
to insert a notice that the affected .c source file has been modified.
This all sounds good. One little thing: the step (3) notice must contain
a relevant date, as per GPL section 5(a).
Thanks for asking about this.
