1521 \`configure' configures this package to adapt to many kinds of systems.

1523 Usage: $0 [OPTION]... [VAR=VALUE]...
1524
1525 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1526 VAR=VALUE.  See below for descriptions of some of the useful variables.
1527
1528 Defaults for the options are specified in brackets.
1529
1530 Configuration:
1531   -h, --help              display this help and exit
1532       --help=short        display options specific to this package
1533       --help=recursive    display the short help of all the included packages
1534   -V, --version           display version information and exit
1535   -q, --quiet, --silent   do not print \`checking...' messages
1536       --cache-file=FILE   cache test results in FILE [disabled]
1537   -C, --config-cache      alias for \`--cache-file=config.cache'
1538   -n, --no-create         do not create output files
1539       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1540
1541 Installation directories:
1542   --prefix=PREFIX         install architecture-independent files in PREFIX

1544   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1545                           [PREFIX]
1546
1547 By default, \`make install' will install all the files in
1548 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1549 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1550 for instance \`--prefix=\$HOME'.
