  51 Options:
  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.
