1455 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1456
1457 Usage: $0 [OPTION]... [VAR=VALUE]...
1458
1459 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1460 VAR=VALUE.  See below for descriptions of some of the useful variables.
1461
1462 Defaults for the options are specified in brackets.
1463
1464 Configuration:
1465   -h, --help              display this help and exit
1466       --help=short        display options specific to this package
1467       --help=recursive    display the short help of all the included packages
1468   -V, --version           display version information and exit
1469   -q, --quiet, --silent   do not print \`checking...' messages
1470       --cache-file=FILE   cache test results in FILE [disabled]
1471   -C, --config-cache      alias for \`--cache-file=config.cache'
1472   -n, --no-create         do not create output files
1473       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1474
1475 Installation directories:
1476   --prefix=PREFIX         install architecture-independent files in PREFIX
1477                           [$ac_default_prefix]
1478   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1479                           [PREFIX]
1480
1481 By default, \`make install' will install all the files in
1482 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1483 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1484 for instance \`--prefix=\$HOME'.
1485
1486 For better control, use the options below.
