Usage: nix-generate-patches NAR-DIR PATCH-DIR PATCH-URI OLD-MANIFEST NEW-MANIFEST
This command generates binary patches between NAR files listed in
OLD-MANIFEST and NEW-MANIFEST. The patches are written to the
directory PATCH-DIR, and the prefix PATCH-URI is used to generate URIs
for the patches. The patches are added to NEW-MANIFEST. All NARs are
required to exist in NAR-DIR. Patches are generated between
succeeding versions of packages with the same name.
