1442 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1443
1444 Usage: $0 [OPTION]... [VAR=VALUE]...
1445
1446 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1447 VAR=VALUE.  See below for descriptions of some of the useful variables.
1448
1449 Defaults for the options are specified in brackets.
1450
1451 Configuration:
1452   -h, --help              display this help and exit
1453       --help=short        display options specific to this package
1454       --help=recursive    display the short help of all the included packages
1455   -V, --version           display version information and exit
1456   -q, --quiet, --silent   do not print \`checking...' messages
1457       --cache-file=FILE   cache test results in FILE [disabled]
1458   -C, --config-cache      alias for \`--cache-file=config.cache'
1459   -n, --no-create         do not create output files
1460       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1461
1462 Installation directories:
1463   --prefix=PREFIX         install architecture-independent files in PREFIX
1464                           [$ac_default_prefix]
1465   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1466                           [PREFIX]
1467
1468 By default, \`make install' will install all the files in
1469 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1470 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1471 for instance \`--prefix=\$HOME'.
1472
1473 For better control, use the options below.
