1449 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1450
1451 Usage: $0 [OPTION]... [VAR=VALUE]...
1452
1453 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1454 VAR=VALUE.  See below for descriptions of some of the useful variables.
1455
1456 Defaults for the options are specified in brackets.
1457
1458 Configuration:
1459   -h, --help              display this help and exit
1460       --help=short        display options specific to this package
1461       --help=recursive    display the short help of all the included packages
1462   -V, --version           display version information and exit
1463   -q, --quiet, --silent   do not print \`checking...' messages
1464       --cache-file=FILE   cache test results in FILE [disabled]
1465   -C, --config-cache      alias for \`--cache-file=config.cache'
1466   -n, --no-create         do not create output files
1467       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1468
1469 Installation directories:
1470   --prefix=PREFIX         install architecture-independent files in PREFIX
1471                           [$ac_default_prefix]
1472   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1473                           [PREFIX]
1474
1475 By default, \`make install' will install all the files in
1476 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1477 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1478 for instance \`--prefix=\$HOME'.
1479
1480 For better control, use the options below.
