1478 \`configure' configures this package to adapt to many kinds of systems.
1480 Usage: $0 [OPTION]... [VAR=VALUE]...
1482 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1483 VAR=VALUE. See below for descriptions of some of the useful variables.
1485 Defaults for the options are specified in brackets.
1488 -h, --help display this help and exit
1489 --help=short display options specific to this package
1490 --help=recursive display the short help of all the included packages
1491 -V, --version display version information and exit
1492 -q, --quiet, --silent do not print \`checking...' messages
1493 --cache-file=FILE cache test results in FILE [disabled]
1494 -C, --config-cache alias for \`--cache-file=config.cache'
1495 -n, --no-create do not create output files
1496 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1498 Installation directories:
1499 --prefix=PREFIX install architecture-independent files in PREFIX
1500 [$ac_default_prefix]
1501 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1504 By default, \`make install' will install all the files in
1505 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1506 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1507 for instance \`--prefix=\$HOME'.
1509 For better control, use the options below.
