1342 \`configure' configures DHCP 4.3.4 to adapt to many kinds of systems.
1343
1344 Usage: $0 [OPTION]... [VAR=VALUE]...
1345
1346 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1347 VAR=VALUE.  See below for descriptions of some of the useful variables.
1348
1349 Defaults for the options are specified in brackets.
1350
1351 Configuration:
1352   -h, --help              display this help and exit
1353       --help=short        display options specific to this package
1354       --help=recursive    display the short help of all the included packages
1355   -V, --version           display version information and exit
1356   -q, --quiet, --silent   do not print \`checking ...' messages
1357       --cache-file=FILE   cache test results in FILE [disabled]
1358   -C, --config-cache      alias for \`--cache-file=config.cache'
1359   -n, --no-create         do not create output files
1360       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1361
1362 Installation directories:
1363   --prefix=PREFIX         install architecture-independent files in PREFIX
1364                           [$ac_default_prefix]
1365   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1366                           [PREFIX]
1367
1368 By default, \`make install' will install all the files in
1369 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1370 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1371 for instance \`--prefix=\$HOME'.
1372
1373 For better control, use the options below.
1374
1375 Fine tuning of the installation directories:
1376   --bindir=DIR            user executables [EPREFIX/bin]
1377   --sbindir=DIR           system admin executables [EPREFIX/sbin]
1378   --libexecdir=DIR        program executables [EPREFIX/libexec]
1379   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
1380   --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
1381   --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
1382   --libdir=DIR            object code libraries [EPREFIX/lib]
1383   --includedir=DIR        C header files [PREFIX/include]

1502 Some influential environment variables:
1503   CC          C compiler command
1504   CFLAGS      C compiler flags
1505   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1506               nonstandard directory <lib dir>
1507   LIBS        libraries to pass to the linker, e.g. -l<library>
1508   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1509               you have headers in a nonstandard directory <include dir>
1510   CPP         C preprocessor
1511
1512 Use these variables to override the choices made by `configure' or to help
1513 it to find libraries and programs with nonstandard names/locations.

5708 ### need to look there and potentially overwrite by default (but not if
5709 ### the user configures an alternate value).  LOCALSTATEDIR is totally
5710 ### braindead.  No one uses /usr/local/var/db/ nor /usr/local/var/run, and
5711 ### they would be insane for suggesting it.  We need to look in /var/for
5712 ### 'db' and 'state/dhcp' for db files, and /var/run for pid files by
5713 ### default.
