[bob@tests tar-1.28]$ ./configure --help
`configure' configures GNU tar 1.28 to adapt to many kinds of systems.

Usage: ./configure [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
                          [/usr/local]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' 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    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  YACC        The `Yet Another Compiler Compiler' implementation to use.
              Defaults to the first program found out of: `bison -y', `byacc',
              `yacc'.
  YFLAGS      The list of arguments that will be passed by default to $YACC.
              This script will default YFLAGS to the empty string to avoid a
              default value of `-d' given by some make applications.
  CPP         C preprocessor
  DEFAULT_RMT_DIR
              Define full file name of the directory where to install `rmt'.
              (default: $(libexecdir))
  RSH         Configure absolute path to default remote shell binary
  DEFAULT_ARCHIVE_FORMAT
              Set the default archive format. Allowed values are: V7, OLDGNU,
              USTAR, POSIX, GNU. Default is GNU
  DEFAULT_ARCHIVE
              Set the name of the default archive (default: -)
  DEFAULT_BLOCKING
              Define default blocking factor (default: 20)
  DEFAULT_QUOTING_STYLE
              Set the default quoting style. Allowed values are: literal,
              shell, shell-always, c, escape, locale, clocale . Default is
              "escape".

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
