  \`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]
    --libexecdir=DIR       program executables [EPREFIX/libexec]
    --datadir=DIR          read-only architecture-independent data [PREFIX/share]
    --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]
    --sharedstatedir=DIR   modifiable architecture-independent data [PREFIX/com]
    --localstatedir=DIR    modifiable single-machine data [PREFIX/var]

  Some influential environment variables:
    CXX         C++ compiler command
    CXXFLAGS    C++ compiler flags
    LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
                nonstandard directory <lib dir>
    CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
                headers in a nonstandard directory <include dir>
    CC          C compiler command
    CFLAGS      C compiler flags
    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.
