1353 \`configure' configures DHCP 4.4.2 to adapt to many kinds of systems.
1354
1355 Usage: $0 [OPTION]... [VAR=VALUE]...
1356
1357 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1358 VAR=VALUE.  See below for descriptions of some of the useful variables.
1359
1360 Defaults for the options are specified in brackets.
1361
1362 Configuration:
1363   -h, --help              display this help and exit
1364       --help=short        display options specific to this package
1365       --help=recursive    display the short help of all the included packages
1366   -V, --version           display version information and exit
1367   -q, --quiet, --silent   do not print \`checking ...' messages
1368       --cache-file=FILE   cache test results in FILE [disabled]
1369   -C, --config-cache      alias for \`--cache-file=config.cache'
1370   -n, --no-create         do not create output files
1371       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1372
1373 Installation directories:
1374   --prefix=PREFIX         install architecture-independent files in PREFIX
1375                           [$ac_default_prefix]
1376   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1377                           [PREFIX]
1378
1379 By default, \`make install' will install all the files in
1380 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1381 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1382 for instance \`--prefix=\$HOME'.
1383
1384 For better control, use the options below.
1385
1386 Fine tuning of the installation directories:
1387   --bindir=DIR            user executables [EPREFIX/bin]
1388   --sbindir=DIR           system admin executables [EPREFIX/sbin]
1389   --libexecdir=DIR        program executables [EPREFIX/libexec]
1390   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
1391   --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]

1518 Some influential environment variables:
1519   CC          C compiler command
1520   CFLAGS      C compiler flags
1521   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1522               nonstandard directory <lib dir>
1523   LIBS        libraries to pass to the linker, e.g. -l<library>
1524   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1525               you have headers in a nonstandard directory <include dir>
1526   CPP         C preprocessor
1527
1528 Use these variables to override the choices made by `configure' or to help
1529 it to find libraries and programs with nonstandard names/locations.

5713 ### Path fun.  Older versions of DHCP were installed in /usr/sbin, so we
5714 ### need to look there and potentially overwrite by default (but not if
5715 ### the user configures an alternate value).  LOCALSTATEDIR is totally
5716 ### braindead.  No one uses /usr/local/var/db/ nor /usr/local/var/run, and
5717 ### they would be insane for suggesting it.  We need to look in /var/for
5718 ### 'db' and 'state/dhcp' for db files, and /var/run for pid files by
5719 ### default.
