+Usage: configure [options]
+This is GNU configure-like front end for a metaconfig-generated Configure.
+It emulates the following GNU configure options (must be fully spelled out):
+       --help
+       --no-create
+       --prefix=PREFIX
+       --quiet
+       --silent
+       --verbose
+       --version
+
+And it honours these environment variables: CC, CFLAGS and DEFS.
