1519 \`configure' configures this package to adapt to many kinds of systems.

1521 Usage: $0 [OPTION]... [VAR=VALUE]...
1522
1523 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1524 VAR=VALUE.  See below for descriptions of some of the useful variables.
1525
1526 Defaults for the options are specified in brackets.
1527
1528 Configuration:
1529   -h, --help              display this help and exit
1530       --help=short        display options specific to this package
1531       --help=recursive    display the short help of all the included packages
1532   -V, --version           display version information and exit
1533   -q, --quiet, --silent   do not print \`checking...' messages
1534       --cache-file=FILE   cache test results in FILE [disabled]
1535   -C, --config-cache      alias for \`--cache-file=config.cache'
1536   -n, --no-create         do not create output files
1537       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1538
1539 Installation directories:
1540   --prefix=PREFIX         install architecture-independent files in PREFIX

1542   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1543                           [PREFIX]
1544
1545 By default, \`make install' will install all the files in
1546 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1547 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1548 for instance \`--prefix=\$HOME'.
