42This is GNU configure-like front end for a metaconfig-generated Configure.
43It emulates the following GNU configure options (must be fully spelled out):
44 --help
45 --no-create
46 --prefix=PREFIX
bab46255 47 --cache-file (ignored)
774d564b
PP
48 --quiet
49 --silent
50 --verbose
51 --version
52
53And it honours these environment variables: CC, CFLAGS and DEFS.
