;;
+;; Anatomy of Racket:
+;; ------------------
+;;
+;; The main Racket Git repository (<https://github.com/racket/racket>) is
+;; organized broadly like this:
+;;
+;; .
+;; ├── Makefile
+;; ├── pkgs/
+;; └── racket/
+;; ├── collects/
+;; └── src/
+;; ├── configure
+;; ├── Makefile.in
+;; ├── bc/
+;; ├── cs/
+;; ├── ChezScheme/
+;; └── ...
+;;
+;; The 'racket/src/' directory contains the source of the runtime system, core
+;; compiler, and primitives for the major Racket implementations: this layer
+;; is called the ``Racket VM''. It is basically a normal autotools
+;; project. (Even when Racket VM implementations use components implemented in
+;; Racket, they are compiled in special modes to produce VM primitives.)
+;; (There are or have been experimental Racket VM implementations elsewhere,
+;; e.g. <https://github.com/pycket/pycket>.)
+;;
+;; The 'racket/collects/' directory contains ``built in'' Racket libraries
+;; that are not part of any package, including the implementation of
+;; 'racket/base': in particular, it must contain enough to implement `raco pkg
+;; install'. It is theoretically possible to use the Racket VM layer without
+;; the main collections, but it is not stable or useful.
+;;
+;; The 'pkgs/' directory contains Racket packages that are especially closely
+;; tied to the implementation of the Racket VM, including 'compiler-lib',
+;; 'racket-doc', and 'racket-test'. Some of these packages depend on Racket
+;; packages that are developed in other Git repositories, predominantly but
+;; not exclusively under the 'racket' GitHub organization. Conversely, not all
+;; of the packages developed in the main Git repository are part of the main
+;; Racket distribution. (Additionally, components of the Racket VM that are
+;; implemented in Racket can be installed as packages, mostly for ease of
+;; development.)
+;;
+;; The top-level 'Makefile' is more like a directory of scripts: it has
+;; convienience targets for developing Racket, and it cooperates with the
+;; 'distro-build' package to assemble custom Racket distributions. It is not
+;; part of Racket source distributions: the root of a source distribution is
+;; basically 'racket/src' with some extra package sources and configuration
+;; added.
+;;
+;; A ''minimal Racket'' installation includes two packages: 'base', which is a
+;; sort of bridge between the current ``built-in'' collections and the package
+;; system's model of dependencies, and 'racket-lib', which, for installations
+;; that can not rely on a system package manager, pulls in the SQLite and
+;; OpenSSL shared libraries as platform-specific dependencies for use by the
+;; ``built-in'' collections.
+;;
+;; The main Racket distribution consists of installing the 'main-distribution'
+;; package and all of its dependencies.
+;;
+;; The default mode when building Racket (or installing it with the released
+;; installers) is an ``in-place build'', which produces a self-contained,
+;; relocatable, roughly FHS-like directory. (Racket also supports
+;; ``Unix-style'' installations, which rearrange the parts of an in-place
+;; build into Racket-specific subdirectories and generally tries to work for
+;; installation into an FHS-based system.) Certain tools, e.g. 'distro-build'
+;; and 'raco cross', are able to work with an in-place Racket build.
+;;
+;; This file defines the packages 'racket-vm-cgc', 'racket-vm-bc', and
+;; 'racket-vm-cs'. All three are in-place builds of 'racket/src/' and
+;; 'racket/collects/' and are installed to 'opt/racket-vm/' in the store
+;; output. The function 'racket-vm-for-system' returns the recomended Racket
+;; VM package for a given system.
+;;
+;; The file 'racket.scm' builds on these packages to define 'racket-minimal'
+;; and 'racket' packages. These use Racket's support for ``layered
+;; installations'', which allow an immutable base layer to be extended with
+;; additional packages. They use the layer configuration directly provide
+;; ready-to-install FHS-like trees, rather than relying on the built in
+;; ``Unix-style install'' mechanism.
+;;
+;; Bootstrapping Racket:
+;; ---------------------
+;;
+;; Here's how bootstrapping Racket works:
+;;
+;; - Racket BC [CGC] can be built with only a C compiler (except for
+;; one caveat discussed below).
+;; - Racket BC [3M] needs an existing Racket to run "xform",
+;; which transforms its own C source code to add additional annotations
+;; for the precise garbage collector.
+;; - Racket CS needs (bootfiles for) Racket's fork of Chez Scheme.
+;; It also needs an existing Racket to compile Racket-implemented
+;; parts of the runtime system to R6RS libraries.
+;; - Chez Scheme also needs bootfiles for itself, but Racket can simulate
+;; enough of Chez Scheme to load Racket's fork of the Chez Scheme compiler
+;; purely from source into Racket and apply the compiler to itself,
+;; producing the needed bootfiles (albeit very slowly).
+;; Any variant of Racket since version 7.1 can run the simulation.
+;;
+;; So, we build CGC to build 3M to build bootfiles and CS.
+;;
+;; (Note: since the CGC variant is basically only for bootstrapping, we
+;; often use "BC" to mean "3M", consistent with `(banner)` and the
+;; suffixes used on executables when more than one variant co-exists.)
+;;
+;; One remaining bootstrapping limitation is that Racket's reader, module
+;; system, and macro expander are implemented in Racket. For Racket CS,
+;; they are compiled to R6RS libraries as discussed above. This note from the
+;; README file applies to all such subsystems:
+;;
+;; The Racket version must be practically the same as the current Racket
+;; verson, although it can be the Racket BC implementation (instead of
+;; the Racket CS implementation).
+;;
+;; Unlike Chez Scheme boot files, the files generated in "schemified"
+;; are human-readable and -editable Scheme code. That provides a way
+;; out of bootstrapping black holes, even without BC.
+;;
+;; However, other Racket subsystems implemented in Racket for Racket CS
+;; use older C implementations for Racket BC, whereas the reader, expander,
+;; and module system were completely replaced with the Racket implementation
+;;
+;; For Racket BC, the compiled "linklet" s-expressions (primitive modules)
+;; are embeded in C as a static string constant. Eventually, they are further
+;; compiled by the C-implemented Racket BC bytecode and JIT compilers.
+;; (On platforms where Racket BC's JIT is not supported, yet another compiler
+;; instead compiles the linklets to C code, but this is not a bootstrapping
+;; issue.)
