1512 \`configure' configures this package to adapt to many kinds of systems.

1514 Usage: $0 [OPTION]... [VAR=VALUE]...
1515
1516 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1517 VAR=VALUE.  See below for descriptions of some of the useful variables.
1518
1519 Defaults for the options are specified in brackets.
1520
1521 Configuration:
1522   -h, --help              display this help and exit
1523       --help=short        display options specific to this package
1524       --help=recursive    display the short help of all the included packages
1525   -V, --version           display version information and exit
1526   -q, --quiet, --silent   do not print \`checking...' messages
1527       --cache-file=FILE   cache test results in FILE [disabled]
1528   -C, --config-cache      alias for \`--cache-file=config.cache'
1529   -n, --no-create         do not create output files
1530       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1531
1532 Installation directories:
1533   --prefix=PREFIX         install architecture-independent files in PREFIX
1534                           [$ac_default_prefix]
1535   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1536                           [PREFIX]
1537
1538 By default, \`make install' will install all the files in
1539 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1540 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1541 for instance \`--prefix=\$HOME'.
