Options:

    -conf FILE  Use the named config file FILE instead of the default.

    -debug      Verbose output debugging on stderr.

    -internal   Generate code that is to be built as part of OpenSSL itself.
                Also scans internal list of files.

    -strict     If any error was found, fail with exit code 1, otherwise 0.

    -help       Show this help text.

    ...         Additional arguments are added to the file list to scan,
                if '-internal' was NOT specified on the command line.
