+@item
+Continuation attachments
+@item
+Parallel garbage collection, in-place garbage collection for old-generation

+@item
+Ordered finalization, immobile (but collectable) objects, weak/ephemeron
+generic hash tables, and reference bytevectors

+ (synopsis "Chez Scheme bootfiles bootstrapped by Racket")
+ (description "Chez Scheme is a self-hosting compiler: building it
+requires ``bootfiles'' containing the Scheme-implemented portions compiled for
+the current platform. (Chez can then cross-compile bootfiles for all other
+supported platforms.)
+
+The Racket package @code{cs-bootstrap} (part of the main Racket Git
+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.")))
