1162 \`configure' configures cluster_expansion 0.1 to adapt to many kinds of systems.
1163
1164 Usage: $0 [OPTION]... [VAR=VALUE]...
1165
1166 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1167 VAR=VALUE.  See below for descriptions of some of the useful variables.
1168
1169 Defaults for the options are specified in brackets.
1170
1171 Configuration:
1172   -h, --help              display this help and exit
1173       --help=short        display options specific to this package
1174       --help=recursive    display the short help of all the included packages
1175   -V, --version           display version information and exit
1176   -q, --quiet, --silent   do not print \`checking...' messages
1177       --cache-file=FILE   cache test results in FILE [disabled]
1178   -C, --config-cache      alias for \`--cache-file=config.cache'
1179   -n, --no-create         do not create output files
1180       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1181
1182 Installation directories:
1183   --prefix=PREFIX         install architecture-independent files in PREFIX
1184                           [$ac_default_prefix]
1185   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1186                           [PREFIX]
1187
1188 By default, \`make install' will install all the files in
1189 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1190 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1191 for instance \`--prefix=\$HOME'.
1192
1193 For better control, use the options below.
1194
1195 Fine tuning of the installation directories:
1196   --bindir=DIR           user executables [EPREFIX/bin]
1197   --sbindir=DIR          system admin executables [EPREFIX/sbin]

1203   --includedir=DIR       C header files [PREFIX/include]

1234   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
1235   --disable-dependency-tracking  speeds up one-time build
1236   --enable-dependency-tracking   do not reject slow dependency extractors
1237
1238 Some influential environment variables:
1239   CC          C compiler command
1240   CFLAGS      C compiler flags
1241   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1242               nonstandard directory <lib dir>
1243   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1244               you have headers in a nonstandard directory <include dir>
1245   CXX         C++ compiler command
1246   CXXFLAGS    C++ compiler flags
1247
1248 Use these variables to override the choices made by `configure' or to help
1249 it to find libraries and programs with nonstandard names/locations.
