+\`make.sh' drives the SBCL build.
+
+Usage: $0 [OPTION]...
+
+ Important: make.sh does not currently control the entirety of the
+ build: configuration file customize-target-features.lisp and certain
+ environment variables play a role as well. see file INSTALL for
+ details.
+
+Options:
+ -h, --help Display this help and exit.
+
+ --prefix=<path> Specify the install location.
+
+ Script install.sh installs SBCL under the specified prefix
+ path: runtime as prefix/bin/sbcl, additional files under
+ prefix/lib/sbcl, and documentation under prefix/share.
+
+ This option also affects the binaries: built-in default for
+ SBCL_HOME is: prefix/lib/sbcl/
+
+ Default prefix is: /usr/local
+
+ --dynamic-space-size=<size> Default dynamic-space size for target.
+
+ This specifies the default dynamic-space size for the SBCL
+ being built. If you need to control the dynamic-space size
+ of the host SBCL, use the --xc-host option.
+
+ If not provided, the default is platform-specific. <size> is
+ taken to be megabytes unless explicitly suffixed with Gb in
+ order to specify the size in gigabytes.
+
+ --with-<feature> Build with specified feature.
+ --without-<feature> Build wihout the specfied feature.
+
+ --fancy Build with several optional features:
+
+ $FANCY_FEATURES
+
+ Plus threading on platforms which support it.
+
+ --arch=<string> Specify the architecture to build for.
+
+ Mainly for doing x86 builds on x86-64.
+
+ --xc-host=<string> Specify the Common Lisp compilation host.
+
+ The string provided should be a command to invoke the
+ cross-compilation Lisp system in such a way, that it reads
+ commands from standard input, and terminates when it reaches end
+ of file on standard input.
+
+ Examples:
+
+ "sbcl --disable-debugger --no-sysinit --no-userinit"
+ Use an existing SBCL binary as a cross-compilation
+ host even though you have stuff in your
+ initialization files which makes it behave in such a
+ non-standard way that it keeps the build from
+ working. Also disable the debugger instead of
+ waiting endlessly for a programmer to help it out
+ with input on *DEBUG-IO*. (This is the default.)
+
+ "sbcl"
+ Use an existing SBCL binary as a cross-compilation
+ host, including your initialization files and
+ building with the debugger enabled. Not recommended
+ for casual users.
+
+ "lisp -noinit -batch"
+ Use an existing CMU CL binary as a cross-compilation
+ host when you have weird things in your .cmucl-init
+ file.
