-+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

-+  --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'.
