1178 \`configure' configures cluster_expansion 0.1 to adapt to many kinds of systems.
1179
1180 Usage: $0 [OPTION]... [VAR=VALUE]...
1181
1182 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1183 VAR=VALUE.  See below for descriptions of some of the useful variables.
1184
1185 Defaults for the options are specified in brackets.
1186
1187 Configuration:
1188   -h, --help              display this help and exit
1189       --help=short        display options specific to this package
1190       --help=recursive    display the short help of all the included packages
1191   -V, --version           display version information and exit
1192   -q, --quiet, --silent   do not print \`checking...' messages
1193       --cache-file=FILE   cache test results in FILE [disabled]
1194   -C, --config-cache      alias for \`--cache-file=config.cache'
1195   -n, --no-create         do not create output files
1196       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1197
1198 Installation directories:
1199   --prefix=PREFIX         install architecture-independent files in PREFIX
1200                           [$ac_default_prefix]
1201   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1202                           [PREFIX]
1203
1204 By default, \`make install' will install all the files in
1205 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1206 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1207 for instance \`--prefix=\$HOME'.
1208
1209 For better control, use the options below.
1210
1211 Fine tuning of the installation directories:
1212   --bindir=DIR           user executables [EPREFIX/bin]
1213   --sbindir=DIR          system admin executables [EPREFIX/sbin]
1214   --libexecdir=DIR       program executables [EPREFIX/libexec]

1219   --includedir=DIR       C header files [PREFIX/include]

1250   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
1251   --disable-dependency-tracking  speeds up one-time build
1252   --enable-dependency-tracking   do not reject slow dependency extractors
1253
1254 Some influential environment variables:
1255   CC          C compiler command
1256   CFLAGS      C compiler flags
1257   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1258               nonstandard directory <lib dir>
1259   LIBS        libraries to pass to the linker, e.g. -l<library>
1260   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1261               you have headers in a nonstandard directory <include dir>
1262   CXX         C++ compiler command
1263   CXXFLAGS    C++ compiler flags
1264
1265 Use these variables to override the choices made by `configure' or to help
1266 it to find libraries and programs with nonstandard names/locations.
