+  ;; The last "upstream" commit is from about 2008, but the Debian maintainers
+  ;; have effectively become the upstream with an extensive series of patches.
+  ;; However, the patches are stored "unapplied", and some enhancements (like
+  ;; a decade's worth of new data files) rely on the Debian packaging tools,
+  ;; so building normally even from the patched sources would miss them.
+  ;; Here, we do all of the patching in the origin, so that the result of
+  ;; `guix build --source` is actually useable for building without Guix.
