1517 \`configure' configures this package to adapt to many kinds of systems.

1519 Usage: $0 [OPTION]... [VAR=VALUE]...
1520
1521 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1522 VAR=VALUE.  See below for descriptions of some of the useful variables.
1523
1524 Defaults for the options are specified in brackets.
1525
1526 Configuration:
1527   -h, --help              display this help and exit
1528       --help=short        display options specific to this package
1529       --help=recursive    display the short help of all the included packages
1530   -V, --version           display version information and exit
1531   -q, --quiet, --silent   do not print \`checking...' messages
1532       --cache-file=FILE   cache test results in FILE [disabled]
1533   -C, --config-cache      alias for \`--cache-file=config.cache'
1534   -n, --no-create         do not create output files
1535       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1536
1537 Installation directories:
1538   --prefix=PREFIX         install architecture-independent files in PREFIX
1539                           [$ac_default_prefix]
1540   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1541                           [PREFIX]
1542
1543 By default, \`make install' will install all the files in
1544 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1545 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1546 for instance \`--prefix=\$HOME'.
1547
