1612 Usage: $0 [OPTION]... [VAR=VALUE]...
1613
1614 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1615 VAR=VALUE.  See below for descriptions of some of the useful variables.
1616
1617 Defaults for the options are specified in brackets.
1618
1619 Configuration:
1620   -h, --help              display this help and exit
1621       --help=short        display options specific to this package
1622       --help=recursive    display the short help of all the included packages
1623   -V, --version           display version information and exit
1624   -q, --quiet, --silent   do not print \`checking ...' messages
1625       --cache-file=FILE   cache test results in FILE [disabled]
1626   -C, --config-cache      alias for \`--cache-file=config.cache'
1627   -n, --no-create         do not create output files
1628       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1629
1630 Installation directories:
1631   --prefix=PREFIX         install architecture-independent files in PREFIX
1632                           [$ac_default_prefix]
1633   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1634                           [PREFIX]
1635
1636 By default, \`make install' will install all the files in
1637 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1638 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1639 for instance \`--prefix=\$HOME'.
