1445 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1446
1447 Usage: $0 [OPTION]... [VAR=VALUE]...
1448
1449 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1450 VAR=VALUE.  See below for descriptions of some of the useful variables.
1451
1452 Defaults for the options are specified in brackets.
1453
1454 Configuration:
1455   -h, --help              display this help and exit
1456       --help=short        display options specific to this package
1457       --help=recursive    display the short help of all the included packages
1458   -V, --version           display version information and exit
1459   -q, --quiet, --silent   do not print \`checking...' messages
1460       --cache-file=FILE   cache test results in FILE [disabled]
1461   -C, --config-cache      alias for \`--cache-file=config.cache'
1462   -n, --no-create         do not create output files
1463       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1464
1465 Installation directories:
1466   --prefix=PREFIX         install architecture-independent files in PREFIX
1467                           [$ac_default_prefix]
1468   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1469                           [PREFIX]
1470
1471 By default, \`make install' will install all the files in
1472 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1473 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1474 for instance \`--prefix=\$HOME'.
1475
1476 For better control, use the options below.

1479   --bindir=DIR            user executables [EPREFIX/bin]
