1352 \`configure' configures DHCP 4.4.0b1 to adapt to many kinds of systems.
1353
1354 Usage: $0 [OPTION]... [VAR=VALUE]...
1355
1356 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1357 VAR=VALUE.  See below for descriptions of some of the useful variables.
1358
1359 Defaults for the options are specified in brackets.
1360
1361 Configuration:
1362   -h, --help              display this help and exit
1363       --help=short        display options specific to this package
1364       --help=recursive    display the short help of all the included packages
1365   -V, --version           display version information and exit
1366   -q, --quiet, --silent   do not print \`checking ...' messages
1367       --cache-file=FILE   cache test results in FILE [disabled]
1368   -C, --config-cache      alias for \`--cache-file=config.cache'
1369   -n, --no-create         do not create output files
1370       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1371
1372 Installation directories:
1373   --prefix=PREFIX         install architecture-independent files in PREFIX
1374                           [$ac_default_prefix]
1375   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1376                           [PREFIX]
1377
1378 By default, \`make install' will install all the files in
1379 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1380 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1381 for instance \`--prefix=\$HOME'.
1382
1383 For better control, use the options below.
1384
1385 Fine tuning of the installation directories:
1386   --bindir=DIR            user executables [EPREFIX/bin]
1387   --sbindir=DIR           system admin executables [EPREFIX/sbin]
1388   --libexecdir=DIR        program executables [EPREFIX/libexec]
1389   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
1390   --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]

1517 Some influential environment variables:
1518   CC          C compiler command
1519   CFLAGS      C compiler flags
1520   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1521               nonstandard directory <lib dir>
1522   LIBS        libraries to pass to the linker, e.g. -l<library>
1523   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1524               you have headers in a nonstandard directory <include dir>
1525   CPP         C preprocessor
1526
1527 Use these variables to override the choices made by `configure' or to help
1528 it to find libraries and programs with nonstandard names/locations.

5720 ### Path fun.  Older versions of DHCP were installed in /usr/sbin, so we
5721 ### need to look there and potentially overwrite by default (but not if
5722 ### the user configures an alternate value).  LOCALSTATEDIR is totally
5723 ### braindead.  No one uses /usr/local/var/db/ nor /usr/local/var/run, and
5724 ### they would be insane for suggesting it.  We need to look in /var/for
5725 ### 'db' and 'state/dhcp' for db files, and /var/run for pid files by
5726 ### default.
