1209 \`configure' configures this package to adapt to many kinds of systems.

1211 Usage: $0 [OPTION]... [VAR=VALUE]...
1212
1213 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1214 VAR=VALUE.  See below for descriptions of some of the useful variables.
1215
1216 Defaults for the options are specified in brackets.
1217
1218 Configuration:
1219   -h, --help              display this help and exit
1220       --help=short        display options specific to this package
1221       --help=recursive    display the short help of all the included packages
1222   -V, --version           display version information and exit
1223   -q, --quiet, --silent   do not print \`checking ...' messages
1224       --cache-file=FILE   cache test results in FILE [disabled]
1225   -C, --config-cache      alias for \`--cache-file=config.cache'
1226   -n, --no-create         do not create output files
1227       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1228
1229 Installation directories:
1230   --prefix=PREFIX         install architecture-independent files in PREFIX
1231                           [$ac_default_prefix]
1232   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1233                           [PREFIX]
1234
1235 By default, \`make install' will install all the files in
1236 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1237 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1238 for instance \`--prefix=\$HOME'.
1239
1240 For better control, use the options below.

1283                           sometimes confusing) to the casual installer
1284
1285 Some influential environment variables:
1286   CC          C compiler command
1287   CFLAGS      C compiler flags
1288   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1289               nonstandard directory <lib dir>
1290   LIBS        libraries to pass to the linker, e.g. -l<library>
1291   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1292               you have headers in a nonstandard directory <include dir>
1293
1294 Use these variables to override the choices made by `configure' or to help
1295 it to find libraries and programs with nonstandard names/locations.
