;; Commentary:
;;
;; The bootstrapping paths for Chez Scheme and Racket are closely
;; entwined. Racket CS (the default Racket implementation) is based on (a fork
;; of) Chez Scheme. Racket's variant of Chez Scheme shares sources for
;; nanopass and stex with upstream Chez Scheme.
;;
;; Racket's variant of Chez Scheme can be bootstrapped by an older Racket
;; implementation, Racket BC, which can be bootstrapped from C. Porting that
;; code to work with upstream Chez Scheme (or finding an old version that
;; does) is our best hope for some day bootstrapping upstream Chez Scheme from
;; source.

  ;; An alist of alists mapping:

  ;; where:
  ;;  - `os` is a string for the OS part of a Chez Scheme machine type; and
  ;;  - `arch` is a string for the architecture part of a Chez machine type.
  ;;
  ;; The absence of an entry for a given arch--os pair means that neither
  ;; upstream Chez Scheme nor the Racket variant can generate native code for
  ;; that system.  (The Racket variant can still provide support via its
  ;; ``portable bytecode'' backends and optional compilation to C.)  A value
  ;; of `#f` means that upstream Chez Scheme does not support the arch--os
  ;; pair at all, but the Racket variant does.  A list has the same meaning as
  ;; a result from `chez-upstream-features-for-system`.
  ;;
  ;; The arch--os pairs marked "commented out" have been commented out in the
  ;; STeX source for the upstream release notes since the initial release as
  ;; free software, but they are reported to work and/or have been described
  ;; as supported by upstream maintainers.
  ;;
  ;; For this overall approach to make sense, we assume that Racket's variant
  ;; of Chez Scheme can generate native code for a superset of the platforms
  ;; supported upstream, supports threads on all platforms it supports at all
  ;; (because they are needed for Racket), and doesn't need bootstrap
  ;; bootfiles.  Those assumptions have held for several years.

repository) implements enough of a Chez Scheme simulation to load the Chez
Scheme compiler purely from source into Racket and apply the compiler to
itself, thus bootstrapping Chez Scheme.  Bootstrapping takes about 10 times as
long as using an existing Chez Scheme, but @code{cs-bootstrap} supports Racket
7.1 and later, including the Racket BC variant.

Note that the generated bootfiles are specific to Racket's fork of Chez
Scheme, and @code{cs-bootstrap} does not currently support building upstream
Chez Scheme.")))
