+\`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.
+
+ --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.
