1593 \`configure' configures this package to adapt to many kinds of systems.
1594
1595 Usage: $0 [OPTION]... [VAR=VALUE]...
1596
1597 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1598 VAR=VALUE. See below for descriptions of some of the useful variables.
1599
1600 Defaults for the options are specified in brackets.
1601
1602 Configuration:
1603 -h, --help display this help and exit
1604 --help=short display options specific to this package
1605 --help=recursive display the short help of all the included packages
1606 -V, --version display version information and exit
1607 -q, --quiet, --silent do not print \`checking ...' messages
1608 --cache-file=FILE cache test results in FILE [disabled]
1609 -C, --config-cache alias for \`--cache-file=config.cache'
1610 -n, --no-create do not create output files
1611 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1612
1613 Installation directories:
1614 --prefix=PREFIX install architecture-independent files in PREFIX
1615 [$ac_default_prefix]
1616 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1617 [PREFIX]
1618
1619 By default, \`make install' will install all the files in
1620 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1621 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1622 for instance \`--prefix=\$HOME'.
1623
1624 For better control, use the options below.
