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               --srcdir=DIRECTORY
    --no-create          --silent
    --prefix=PREFIX      --verbose
    --quiet              --version

And it honours these environment variables: CC, CFLAGS and DEFS.

Furthermore, it ignores the following arguments, when supplied:

    --cache-file=FILE    --target=TARGET
    --enable-*           --with-*
    --host=HOST
