51Options:
52
53  -conf F       Use the config file F instead of the default one:
54                  crypto/err/openssl.ec
55
56  -hprefix P    Prepend the filenames in generated #include <header>
57                statements with prefix P. Default: 'openssl/' (without
58                the quotes, naturally)
59
60  -debug        Turn on debugging verbose output on stderr.
61
62  -rebuild      Rebuild all header and C source files, irrespective of the
63                fact if any error or function codes have been added/removed.
64                Default: only update files for libraries which saw change
65                         (of course, this requires '-write' as well, or no
66                          files will be touched!)
67
68  -recurse      scan a preconfigured set of directories / files for error and
69                function codes:
70                  (<crypto/*.c>, <crypto/*/*.c>, <ssl/*.c>, <apps/*.c>)
71                When this option is NOT specified, the filelist is taken from
72                the commandline instead. Here, wildcards may be embedded. (Be
73                sure to escape those to prevent the shell from expanding them
74                for you when you wish mkerr.pl to do so instead.)
75                Default: take file list to scan from the command line.
76
77  -reindex      Discard the numeric values previously assigned to the error
78                and function codes as extracted from the scanned header files;
79                instead renumber all of them starting from 100. (Note that
80                the numbers assigned through 'R' records in the config file
81                remain intact.)
82                Default: keep previously assigned numbers. (You are warned
83                         when collisions are detected.)
84
85  -nostatic     Generates a different source code, where these additional
86                functions are generated for each library specified in the
87                config file:
88                  void ERR_load_<LIB>_strings(void);
89                  void ERR_unload_<LIB>_strings(void);
90                  void ERR_<LIB>_error(int f, int r, char *fn, int ln);
91                  #define <LIB>err(f,r) ERR_<LIB>_error(f,r,__FILE__,__LINE__)
92                while the code facilitates the use of these in an environment
93                where the error support routines are dynamically loaded at
94                runtime.
95                Default: 'static' code generation.
96
97  -staticloader Prefix generated functions with the 'static' scope modifier.
98                Default: don't write any scope modifier prefix.
99
100  -write        Actually (over)write the generated code to the header and C
101                source files as assigned to each library through the config
102                file.
103                Default: don't write.
104
105  -help / -h / -? / --help            Show this help text.
106
107  ...           Additional arguments are added to the file list to scan,
108                assuming '-recurse' was NOT specified on the command line.
