1379 \`configure' configures this package to adapt to many kinds of systems.
1381 Usage: $0 [OPTION]... [VAR=VALUE]...
1383 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1384 VAR=VALUE. See below for descriptions of some of the useful variables.
1386 Defaults for the options are specified in brackets.
1388 Configuration:
1389 -h, --help display this help and exit
1390 --help=short display options specific to this package
1391 --help=recursive display the short help of all the included packages
1392 -V, --version display version information and exit
1393 -q, --quiet, --silent do not print \`checking...' messages
1394 --cache-file=FILE cache test results in FILE [disabled]
1395 -C, --config-cache alias for \`--cache-file=config.cache'
1396 -n, --no-create do not create output files
1397 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1399 Installation directories:
1400 --prefix=PREFIX install architecture-independent files in PREFIX
1401 [$ac_default_prefix]
1402 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1403 [PREFIX]
1405 By default, \`make install' will install all the files in
1406 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1407 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1408 for instance \`--prefix=\$HOME'.
1410 For better control, use the options below.
1412 Fine tuning of the installation directories:
1413 --bindir=DIR user executables [EPREFIX/bin]
1414 --sbindir=DIR system admin executables [EPREFIX/sbin]
