-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.
