1578 Usage: $0 [OPTION]... [VAR=VALUE]...
1579
1580 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1581 VAR=VALUE.  See below for descriptions of some of the useful variables.
1582
1583 Defaults for the options are specified in brackets.
1584
1585 Configuration:
1586   -h, --help              display this help and exit
1587       --help=short        display options specific to this package
1588       --help=recursive    display the short help of all the included packages
1589   -V, --version           display version information and exit
1590   -q, --quiet, --silent   do not print \`checking ...' messages
1591       --cache-file=FILE   cache test results in FILE [disabled]
1592   -C, --config-cache      alias for \`--cache-file=config.cache'
1593   -n, --no-create         do not create output files
1594       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1595
1596 Installation directories:
1597   --prefix=PREFIX         install architecture-independent files in PREFIX
1598                           [$ac_default_prefix]
1599   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1600                           [PREFIX]
1601
1602 By default, \`make install' will install all the files in
1603 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1604 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1605 for instance \`--prefix=\$HOME'.
