1598 Usage: $0 [OPTION]... [VAR=VALUE]...
1599
1600 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1601 VAR=VALUE.  See below for descriptions of some of the useful variables.
1602
1603 Defaults for the options are specified in brackets.
1604
1605 Configuration:
1606   -h, --help              display this help and exit
1607       --help=short        display options specific to this package
1608       --help=recursive    display the short help of all the included packages
1609   -V, --version           display version information and exit
1610   -q, --quiet, --silent   do not print \`checking ...' messages
1611       --cache-file=FILE   cache test results in FILE [disabled]
1612   -C, --config-cache      alias for \`--cache-file=config.cache'
1613   -n, --no-create         do not create output files
1614       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1615
1616 Installation directories:
1617   --prefix=PREFIX         install architecture-independent files in PREFIX
1618                           [$ac_default_prefix]
1619   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1620                           [PREFIX]
1621
1622 By default, \`make install' will install all the files in
1623 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1624 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1625 for instance \`--prefix=\$HOME'.
1626
1627 For better control, use the options below.
