    \`configure' configures this package 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]
      --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]

      --libdir=DIR           object code libraries [EPREFIX/lib]
      --includedir=DIR       C header files [PREFIX/include]
      --oldincludedir=DIR    C header files for non-gcc [/usr/include]
