1431 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1432
1433 Usage: $0 [OPTION]... [VAR=VALUE]...
1434
1435 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1436 VAR=VALUE.  See below for descriptions of some of the useful variables.
1437
1438 Defaults for the options are specified in brackets.
1439
1440 Configuration:
1441   -h, --help              display this help and exit
1442       --help=short        display options specific to this package
1443       --help=recursive    display the short help of all the included packages
1444   -V, --version           display version information and exit
1445   -q, --quiet, --silent   do not print \`checking...' messages
1446       --cache-file=FILE   cache test results in FILE [disabled]
1447   -C, --config-cache      alias for \`--cache-file=config.cache'
1448   -n, --no-create         do not create output files
1449       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1450
1451 Installation directories:
1452   --prefix=PREFIX         install architecture-independent files in PREFIX
1453                           [$ac_default_prefix]
1454   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1455                           [PREFIX]
1456
1457 By default, \`make install' will install all the files in
1458 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1459 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1460 for instance \`--prefix=\$HOME'.
1461
1462 For better control, use the options below.

1465   --bindir=DIR            user executables [EPREFIX/bin]
