-+  ;; Compute a native or pbarch machine string for the current platform.
-+  ;; Some caveats:
-+  ;;  1. A pbarch Racket will always infer a pbarch machine,
-+  ;;     even if a native machine exists. Hopefully this is an
-+  ;;     unlikely scenario: if you're running Racket CS, you've
-+  ;;     bootstrapped Chez somehow, so you could use `re.boot`.
-+  ;;  2. A `tpb` or `pb` Racket on a 32-bit platform would still return
-+  ;;     64 from `(system-type 'word)`, but, in addition to the above,
-+  ;;     it is not currently possible or desired to build Racket as
-+  ;;     `tpb` or `pb` (as opposed to pbarch variants):
-+  ;;     see <https://github.com/racket/racket/issues/4692>.
-+  ;;  3. On a hypothetical platform where Chez supported both the
-+  ;;     architecture and the OS, but not the combination of the two,
-+  ;;     (e.g. riscv64 Windows) this code would currently return a
-+  ;;     non-existent native machine (e.g. trv64nt) instead of a
-+  ;;     working pbarch machine. Presumably this could be fixed if

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+Configure the release notes page to be rendered separately at every
+installation layer. Otherwise, rendering documentation for packages
+installed in a new layer might try to write to `release/in.sxref`
+in the parent layer’s docs directory.
