36Usage: configure [options]
37This is GNU configure-like front end for a metaconfig-generated Configure.
38It emulates the following GNU configure options (must be fully spelled out):
39
40 --help --srcdir=DIRECTORY
41 --no-create --silent
42 --prefix=PREFIX --verbose
43 --quiet --version
44
45And it honours these environment variables: CC, CFLAGS and DEFS.
46
47Furthermore, it ignores the following arguments, when supplied:
48
49 --cache-file=FILE --target=TARGET
50 --enable-* --with-*
51 --host=HOST
