1530 \`configure' configures package-unused version-unused to adapt to many kinds of systems.
1531
1532 Usage: $0 [OPTION]... [VAR=VALUE]...
1533
1534 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1535 VAR=VALUE.  See below for descriptions of some of the useful variables.
1536
1537 Defaults for the options are specified in brackets.
1538
1539 Configuration:
1540   -h, --help              display this help and exit
1541       --help=short        display options specific to this package
1542       --help=recursive    display the short help of all the included packages
1543   -V, --version           display version information and exit
1544   -q, --quiet, --silent   do not print \`checking ...' messages
1545       --cache-file=FILE   cache test results in FILE [disabled]
1546   -C, --config-cache      alias for \`--cache-file=config.cache'
1547   -n, --no-create         do not create output files
1548       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1549
1550 Installation directories:
1551   --prefix=PREFIX         install architecture-independent files in PREFIX
1552                           [$ac_default_prefix]
1553   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1554                           [PREFIX]
1555
1556 By default, \`make install' will install all the files in
1557 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1558 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1559 for instance \`--prefix=\$HOME'.

1561 For better control, use the options below.
