1579 Usage: $0 [OPTION]... [VAR=VALUE]...
1580
1581 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1582 VAR=VALUE.  See below for descriptions of some of the useful variables.
1583
1584 Defaults for the options are specified in brackets.
1585
1586 Configuration:
1587   -h, --help              display this help and exit
1588       --help=short        display options specific to this package
1589       --help=recursive    display the short help of all the included packages
1590   -V, --version           display version information and exit
1591   -q, --quiet, --silent   do not print \`checking ...' messages
1592       --cache-file=FILE   cache test results in FILE [disabled]
1593   -C, --config-cache      alias for \`--cache-file=config.cache'
1594   -n, --no-create         do not create output files
1595       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1596
1597 Installation directories:
1598   --prefix=PREFIX         install architecture-independent files in PREFIX
1599                           [$ac_default_prefix]
1600   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1601                           [PREFIX]
1602
1603 By default, \`make install' will install all the files in
1604 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1605 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1606 for instance \`--prefix=\$HOME'.
