+\`configure' configures nbsd-digest 20080509 to adapt to many kinds of systems.
 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]
+                          [$ac_default_prefix]
   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-			  [PREFIX]
+                          [PREFIX]
 By default, \`make install' will install all the files in
 \`$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]

 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    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
               you have headers in a nonstandard directory <include dir>
   CPP         C preprocessor
 Use these variables to override the choices made by `configure' or to help
 it to find libraries and programs with nonstandard names/locations.
