1204 \`configure' configures this package to adapt to many kinds of systems.
1205
1206 Usage: $0 [OPTION]... [VAR=VALUE]...
1207
1208 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1209 VAR=VALUE.  See below for descriptions of some of the useful variables.
1210
1211 Defaults for the options are specified in brackets.
1212
1213 Configuration:
1214   -h, --help              display this help and exit
1215       --help=short        display options specific to this package
1216       --help=recursive    display the short help of all the included packages
1217   -V, --version           display version information and exit
1218   -q, --quiet, --silent   do not print \`checking...' messages
1219       --cache-file=FILE   cache test results in FILE [disabled]
1220   -C, --config-cache      alias for \`--cache-file=config.cache'
1221   -n, --no-create         do not create output files
1222       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1223
1224 Installation directories:
1225   --prefix=PREFIX         install architecture-independent files in PREFIX
1226                           [$ac_default_prefix]
1227   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1228                           [PREFIX]
1229
1230 By default, \`make install' will install all the files in
1231 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1232 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1233 for instance \`--prefix=\$HOME'.
1234
1235 For better control, use the options below.

1237 Fine tuning of the installation directories:
1238   --bindir=DIR            user executables [EPREFIX/bin]

1283 Some influential environment variables:
1284   CC          C compiler command
1285   CFLAGS      C compiler flags
1286   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1287               nonstandard directory <lib dir>
1288   LIBS        libraries to pass to the linker, e.g. -l<library>
1289   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
1290               you have headers in a nonstandard directory <include dir>
1291
1292 Use these variables to override the choices made by `configure' or to help
1293 it to find libraries and programs with nonstandard names/locations.
