1451 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1452
1453 Usage: $0 [OPTION]... [VAR=VALUE]...
1454
1455 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1456 VAR=VALUE.  See below for descriptions of some of the useful variables.
1457
1458 Defaults for the options are specified in brackets.
1459
1460 Configuration:
1461   -h, --help              display this help and exit
1462       --help=short        display options specific to this package
1463       --help=recursive    display the short help of all the included packages
1464   -V, --version           display version information and exit
1465   -q, --quiet, --silent   do not print \`checking...' messages
1466       --cache-file=FILE   cache test results in FILE [disabled]
1467   -C, --config-cache      alias for \`--cache-file=config.cache'
1468   -n, --no-create         do not create output files
1469       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1470
1471 Installation directories:
1472   --prefix=PREFIX         install architecture-independent files in PREFIX
1473                           [$ac_default_prefix]
1474   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1475                           [PREFIX]
1476
1477 By default, \`make install' will install all the files in
1478 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1479 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1480 for instance \`--prefix=\$HOME'.
1481
1482 For better control, use the options below.
