1394 \`configure' configures this package to adapt to many kinds of systems.
1396 Usage: $0 [OPTION]... [VAR=VALUE]...
1398 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1399 VAR=VALUE. See below for descriptions of some of the useful variables.
1401 Defaults for the options are specified in brackets.
1403 Configuration:
1404 -h, --help display this help and exit
1405 --help=short display options specific to this package
1406 --help=recursive display the short help of all the included packages
1407 -V, --version display version information and exit
1408 -q, --quiet, --silent do not print \`checking...' messages
1409 --cache-file=FILE cache test results in FILE [disabled]
1410 -C, --config-cache alias for \`--cache-file=config.cache'
1411 -n, --no-create do not create output files
1412 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1414 Installation directories:
1415 --prefix=PREFIX install architecture-independent files in PREFIX
1416 [$ac_default_prefix]
1417 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1418 [PREFIX]
1420 By default, \`make install' will install all the files in
1421 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1422 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1423 for instance \`--prefix=\$HOME'.
1425 For better control, use the options below.
1427 Fine tuning of the installation directories:
1428 --bindir=DIR user executables [EPREFIX/bin]
1429 --sbindir=DIR system admin executables [EPREFIX/sbin]
1430 --libexecdir=DIR program executables [EPREFIX/libexec]
