+
+These variables, exported by @code{(guix build-system sbcl)}, implement
+build procedures for Common Lisp packages using the
+@url{https://common-lisp.net/project/asdf/, ``ASDF''} system.
+
+The @code{asdf-build-system/source} system installs the packages in
+source form, and can be loaded using any common lisp implementation, via
+ASDF. The others, such as @code{asdf-build-system/sbcl}, install binary
+systems in the format which a particular implementation
+understands. These build systems can also be used to produce executable
+programs, or lisp images which contain a set of packages pre-loaded.
+
+The build system uses conventions to determine the roles of inputs in
+the build system. For binary packages, the package itself as well as its
+dependencies should end their name with the lisp implementation, such as
+@code{-sbcl} for @code{asdf-build-system/sbcl}. Additionally, the
+corresponding source package should be labelled using the same name as
+the package, but with this suffix dropped. If it cannot be labelled that
+way, the label can be overriden by the @code{#:source-input} parameter.
+
+One package should be defined for each ASDF system.
+
+The package outputs control whether or not executable programs and
+images are built alongside the package's usual output, using the
+@code{bin} and @code{image} outputs, respectively.
+
+Packages can also be built which combine other packages into an
+executable program or image only, without building another
+system. Specifying one of the @code{#:binary?} or @code{#:image?}
+parameters will produce this behaviour.
+
+When building an executable program, the @code{#:entry-program}
+parameter, which should be a list of Common Lisp expressions, must be
+used to specify what program should be run. In this program,
+@code{arguments} will be bound to the command-line arguments passed.
+
+The @code{#:image-dependencies} parameter can be used to add packages to
+the pre-loaded systems included in the executable program or
+image. @code{#:compile-dependencies} specifies a list of additional
+systems which should be loaded before a system is compiled. If the
+package depends on special systems exported by the implementation
+itself, the @code{#:special-dependencies} parameter should be used to
+specify them.
+
+If a package must modify its source while building, the
+@code{build-in-tree} parameter can specify an output in which the source
+will be stored after the package has been built.
