++
++Usage: $0 [OPTION]... [VAR=VALUE]...
++
++To assign environment variables (e.g., CC, CFLAGS...), specify them as
++VAR=VALUE.  See below for descriptions of some of the useful variables.
++
++Defaults for the options are specified in brackets.
++
++Configuration:
++  -h, --help              display this help and exit
++      --help=short        display options specific to this package
++      --help=recursive    display the short help of all the included packages
++  -V, --version           display version information and exit
++  -q, --quiet, --silent   do not print \`checking ...' messages
++      --cache-file=FILE   cache test results in FILE [disabled]
++  -C, --config-cache      alias for \`--cache-file=config.cache'
++  -n, --no-create         do not create output files
++      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
++
++Installation directories:
++  --prefix=PREFIX         install architecture-independent files in PREFIX
++                          @<:@@S|@ac_default_prefix@:>@
++  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
++                          @<:@PREFIX@:>@
++
++By default, \`make install' will install all the files in
++\`$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]

++  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
++  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
++  --libdir=DIR            object code libraries [EPREFIX/lib]
++  --includedir=DIR        C header files [PREFIX/include]
