-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.
