 101 \`make.sh' drives the SBCL build.
 102
 103 Usage: $0 [OPTION]...
 104
 105   Important: make.sh does not currently control the entirety of the
 106   build: configuration file customize-target-features.lisp and certain
 107   environment variables play a role as well. see file INSTALL for
 108   details.
 109
 110 Options:
 111   -h, --help           Display this help and exit.
 112
 113   --prefix=<path>      Specify the install location.
 114
 115       Script install.sh installs SBCL under the specified prefix
 116       path: runtime as prefix/bin/sbcl, additional files under
 117       prefix/lib/sbcl, and documentation under prefix/share.
 118
 119       This option also affects the binaries: built-in default for
 120       SBCL_HOME is: prefix/lib/sbcl/
 121
 122       Default prefix is: /usr/local
 123
 124   --dynamic-space-size=<size> Specify default dynamic-space size.
 125
 126       If not provided, the default is platform-specific. <size> is
 127       taken to be megabytes unless explicitly suffixed with Gb in
 128       order to specify the size in gigabytes.
 129
 130   --xc-host=<string>   Specify the Common Lisp compilation host.
 131
 132       The string provided should be a command to invoke the
 133       cross-compilation Lisp system in such a way, that it reads
 134       commands from standard input, and terminates when it reaches end
 135       of file on standard input.
 136
 137       Examples:
 138
 139        "sbcl --disable-debugger --no-sysinit --no-userinit"
 140                   Use an existing SBCL binary as a cross-compilation
 141                   host even though you have stuff in your
 142                   initialization files which makes it behave in such a
 143                   non-standard way that it keeps the build from
 144                   working. Also disable the debugger instead of
 145                   waiting endlessly for a programmer to help it out
 146                   with input on *DEBUG-IO*. (This is the default.)
 147
 148        "sbcl"
 149                   Use an existing SBCL binary as a cross-compilation
 150                   host, including your initialization files and
 151                   building with the debugger enabled. Not recommended
 152                   for casual users.
 153
 154        "lisp -noinit -batch"
 155                   Use an existing CMU CL binary as a cross-compilation
 156                   host when you have weird things in your .cmucl-init
 157                   file.
