1375 \`configure' configures unrealircd 6.1.6-rc1 to adapt to many kinds of systems.
1376
1377 Usage: $0 [OPTION]... [VAR=VALUE]...
1378
1379 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1380 VAR=VALUE.  See below for descriptions of some of the useful variables.
1381
1382 Defaults for the options are specified in brackets.
1383
1384 Configuration:
1385   -h, --help              display this help and exit
1386       --help=short        display options specific to this package
1387       --help=recursive    display the short help of all the included packages
1388   -V, --version           display version information and exit
1389   -q, --quiet, --silent   do not print \`checking ...' messages
1390       --cache-file=FILE   cache test results in FILE [disabled]
1391   -C, --config-cache      alias for \`--cache-file=config.cache'
1392   -n, --no-create         do not create output files
1393       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1394
1395 Installation directories:
1396   --prefix=PREFIX         install architecture-independent files in PREFIX
1397                           [$ac_default_prefix]
1398   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1399                           [PREFIX]
1400
1401 By default, \`make install' will install all the files in
1402 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1403 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1404 for instance \`--prefix=\$HOME'.
1405
1406 For better control, use the options below.
1407
1408 Fine tuning of the installation directories:
1409   --bindir=DIR            user executables [EPREFIX/bin]
