5518bc02 43Usage: configure.gnu [options]
774d564b 44This is GNU configure-like front end for a metaconfig-generated Configure.
45It emulates the following GNU configure options (must be fully spelled out):
46 --help
47 --no-create
48 --prefix=PREFIX
bab46255 49 --cache-file (ignored)
774d564b 50 --quiet
51 --silent
52 --verbose
53 --version
54
55And it honours these environment variables: CC, CFLAGS and DEFS.
