1174 \`configure' configures this package to adapt to many kinds of systems.
1175
1176 Usage: $0 [OPTION]... [VAR=VALUE]...
1177
1178 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1179 VAR=VALUE.  See below for descriptions of some of the useful variables.
1180
1181 Defaults for the options are specified in brackets.
1182
1183 Configuration:
1184   -h, --help              display this help and exit
1185       --help=short        display options specific to this package
1186       --help=recursive    display the short help of all the included packages
1187   -V, --version           display version information and exit
1188   -q, --quiet, --silent   do not print \`checking...' messages
1189       --cache-file=FILE   cache test results in FILE [disabled]
1190   -C, --config-cache      alias for \`--cache-file=config.cache'
1191   -n, --no-create         do not create output files
1192       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1193
1194 Installation directories:
1195   --prefix=PREFIX         install architecture-independent files in PREFIX
1196                           [$ac_default_prefix]
1197   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1198                           [PREFIX]
1199
1200 By default, \`make install' will install all the files in
1201 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1202 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1203 for instance \`--prefix=\$HOME'.
1204
1205 For better control, use the options below.
1206
1207 Fine tuning of the installation directories:
1208   --bindir=DIR            user executables [EPREFIX/bin]
1209   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1237 Some influential environment variables:
1238   CC          C compiler command
1239   CFLAGS      C compiler flags
1240   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1241               nonstandard directory <lib dir>
1242   LIBS        libraries to pass to the linker, e.g. -l<library>
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
1246 Use these variables to override the choices made by `configure' or to help
1247 it to find libraries and programs with nonstandard names/locations.
