1582 \`configure' configures this package to adapt to many kinds of systems.

1584 Usage: $0 [OPTION]... [VAR=VALUE]...
1585
1586 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1587 VAR=VALUE.  See below for descriptions of some of the useful variables.
1588
1589 Defaults for the options are specified in brackets.
1590
1591 Configuration:
1592   -h, --help              display this help and exit
1593       --help=short        display options specific to this package
1594       --help=recursive    display the short help of all the included packages
1595   -V, --version           display version information and exit
1596   -q, --quiet, --silent   do not print \`checking ...' messages
1597       --cache-file=FILE   cache test results in FILE [disabled]
1598   -C, --config-cache      alias for \`--cache-file=config.cache'
1599   -n, --no-create         do not create output files
1600       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1601
1602 Installation directories:
1603   --prefix=PREFIX         install architecture-independent files in PREFIX
1604                           [$ac_default_prefix]
1605   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1606                           [PREFIX]
1607
1608 By default, \`make install' will install all the files in
1609 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1610 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1611 for instance \`--prefix=\$HOME'.
