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.
