 139 \`make.sh' drives the SBCL build.
 140
 141 Usage: $0 [OPTION]...
 142
 143   Important: make.sh does not currently control the entirety of the
 144   build: configuration file customize-target-features.lisp and certain
 145   environment variables play a role as well. see file INSTALL for
 146   details.
 147
 148 Options:
 149   -h, --help           Display this help and exit.
 150
 151   --prefix=<path>      Specify the install location.
 152
 153       Script install.sh installs SBCL under the specified prefix
 154       path: runtime as prefix/bin/sbcl, additional files under
 155       prefix/lib/sbcl, and documentation under prefix/share.
 156
 157       This option also affects the binaries: built-in default for
 158       SBCL_HOME is: prefix/lib/sbcl/
 159
 160       Default prefix is: /usr/local
 161
 162   --dynamic-space-size=<size> Default dynamic-space size for target.
 163
 164       This specifies the default dynamic-space size for the SBCL
 165       being built. If you need to control the dynamic-space size
 166       of the host SBCL, use the --xc-host option.
 167
 168       If not provided, the default is platform-specific. <size> is
 169       taken to be megabytes unless explicitly suffixed with Gb in
 170       order to specify the size in gigabytes.
 171
 172   --with-<feature>     Build with specified feature.
 173   --without-<feature>  Build wihout the specfied feature.
 174
 175   --fancy              Build with several optional features:
 176
 177                            $FANCY_FEATURES
 178
 179                        Plus threading on platforms which support it.
 180
 181   --arch=<string>      Specify the architecture to build for.
 182
 183       Mainly for doing x86 builds on x86-64.
 184
 185   --xc-host=<string>   Specify the Common Lisp compilation host.
 186
 187       The string provided should be a command to invoke the
 188       cross-compilation Lisp system in such a way, that it reads
 189       commands from standard input, and terminates when it reaches end
 190       of file on standard input.
 191
 192       Examples:
 193
 194        "sbcl --disable-debugger --no-sysinit --no-userinit"
 195                   Use an existing SBCL binary as a cross-compilation
 196                   host even though you have stuff in your
 197                   initialization files which makes it behave in such a
 198                   non-standard way that it keeps the build from
 199                   working. Also disable the debugger instead of
 200                   waiting endlessly for a programmer to help it out
 201                   with input on *DEBUG-IO*. (This is the default.)
 202
 203        "sbcl"
 204                   Use an existing SBCL binary as a cross-compilation
 205                   host, including your initialization files and
 206                   building with the debugger enabled. Not recommended
 207                   for casual users.
 208
 209        "lisp -noinit -batch"
 210                   Use an existing CMU CL binary as a cross-compilation
 211                   host when you have weird things in your .cmucl-init
 212                   file.
 213
 214   --host-location=<string> Location of the source directory on compilation host
 215
 216       The string is passed to the command rsync to transfer the
 217       necessary files between the target and host directories during
 218       the make-target-*.sh steps of cross-compilation (cf. make.sh)
 219
 220       Examples:
 221
 222        user@host-machine:/home/user/sbcl
 223                   Transfer the files to/from directory /home/user/sbcl
 224                   on host-machine.
