-+ 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.
