Comment (by ncohen):

 Hellooooooo,

 > You advised (see #16711 about upgrade to 3.1.1) adding this file to
 document the renaming of the tarball (from R-x-y-z.tar.gz to
 r-x-y-z.tar.gz), needed by the then-current convention of all-lowercase
 tarball names.

 A `spkg-src` file to document a renaming? Why? `O_o`

 > Do you advise keeping a no-op {{{spkg-src}}} ?

 No. I advise to keep a file that re-builds the archive from network
 ressources only. Then it becomes easier to check that the archive's
 content is what it should be. I do not see anything wrong with a script
 that downloads a distant file (whose url is generated from the locally
 stored version number), and does nothing else to it if there is nothing
 else to do.

 Actually, I will try to solve this once and for all. I'll write some 'sage
 --sanity-check-package whatever' that uses whatever's spkg-src script (if
 any), and checks whether the content of the file in `upstream/` matches
 it.

 This way, checking that the archive is legit will only be a call to
 'sanity-check'. In this setting, your spkg-src, even though it just
 downloads something, will be useful.
