+Cross Compiling
+---------------
+
+If you use `./configure --host=...` to cross compile, then you will
+also need to add something like `CC_FOR_BUILD=cc` as a `./configure`
+argument to specify the compiler for a `zuo` to use on the build
+machine. If necessary, you can also specify `CFLAGS_FOR_BUILD`,

Subject: [PATCH 2/4] Zuo: sort hash keys

Printing in a sorted order is helpful to make things more
deterministic independent of symbol inputs. Making `hash-keys`
produce a sorted list generalizes that determinism.

Subject: [PATCH] Zuo: patch zuo_process for "/bin/sh" on Guix

If:

    1. The nonstandard but ubiquitous macro `_PATH_BSHELL` from
       <paths.h> is defined; and

    2. `zuo_process` is called with the exact path "/bin/sh"; and

    3. The path specified by `_PATH_BSHELL` exists;

then `zuo_process` will execute the file specified by `_PATH_BSHELL`
instead of "/bin/sh".

Checking that the path specified by `_PATH_BSHELL` exists safeguards
against obscure errors if attempting to use stand-alone executables
built by the patched Racket in non-Guix envoronments.

      (description "Zuo (作) is a tiny Racket with primitives for dealing
with files and running processes.  It comes with a @command{make}-like
embedded DSL, which is used to build Racket itself.

Zuo is a Racket variant in the sense that program files start with
@code{#lang}, and the module path after @code{#lang} determines the parsing
and expansion of the file content.  That's how the @command{make}-like DSL is
defined, and even the base Zuo language is defined by layers of @code{#lang}s.
One of the early layers implements macros.")
