+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ --includedir=DIR C header files [PREFIX/include]

+ Directory where the winbind includes may be found
+ --with-winbind-lib-dir=DIR
+ Directory where the winbind libraries may be found

+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if

+ CPP C preprocessor

+
+ This code makes no attempt to be fast! In fact, it is a very
+ slow implementation
+
+ This code is NOT a complete DES implementation. It implements only
+ the minimum necessary for SMB authentication, as used by all SMB
+ products (including every copy of Microsoft Windows95 ever sold)
+
+ In particular, it can only do a unchained forward DES pass. This
+ means it is not possible to use this code for encryption/decryption
+ of data, instead it is only useful as a "hash" algorithm.
+
+ There is no entry point into this code that allows normal DES operation.
+
+ I believe this means that this code does not come under ITAR
+ regulations but this is NOT a legal opinion. If you are concerned
+ about the applicability of ITAR regulations to this code then you
+ should confirm it for yourself (and maybe let me know if you come
+ up with a different answer to the one above)
