+mkerr.pl [options] ...
+
+Options:
+
+  -conf F       Use the config file F instead of the default one:
+                  crypto/err/openssl.ec
+
+  -hprefix P    Prepend the filenames in generated #include <header>
+                statements with prefix P. Default: 'openssl/' (without
+                the quotes, naturally)
+
+  -debug        Turn on debugging verbose output on stderr.
+
+  -rebuild      Rebuild all header and C source files, irrespective of the
+                fact if any error or function codes have been added/removed.
+                Default: only update files for libraries which saw change
+                         (of course, this requires '-write' as well, or no
+                          files will be touched!)
+
+  -recurse      scan a preconfigured set of directories / files for error and
+                function codes:
+                  (<crypto/*.c>, <crypto/*/*.c>, <ssl/*.c>, <apps/*.c>)
+                When this option is NOT specified, the filelist is taken from
+                the commandline instead. Here, wildcards may be embedded. (Be
+                sure to escape those to prevent the shell from expanding them
+                for you when you wish mkerr.pl to do so instead.)
+                Default: take file list to scan from the command line.
+
+  -reindex      Discard the numeric values previously assigned to the error
+                and function codes as extracted from the scanned header files;
+                instead renumber all of them starting from 100. (Note that
+                the numbers assigned through 'R' records in the config file
+                remain intact.)
+                Default: keep previously assigned numbers. (You are warned
+                         when collisions are detected.)
+
+  -nostatic     Generates a different source code, where these additional 
+                functions are generated for each library specified in the
+                config file:
+                  void ERR_load_<LIB>_strings(void);
+                  void ERR_unload_<LIB>_strings(void);
+                  void ERR_<LIB>_error(int f, int r, char *fn, int ln);
+                  #define <LIB>err(f,r) ERR_<LIB>_error(f,r,__FILE__,__LINE__)
+                while the code facilitates the use of these in an environment
+                where the error support routines are dynamically loaded at 
+                runtime.
+                Default: 'static' code generation.
+
+  -staticloader Prefix generated functions with the 'static' scope modifier.
+                Default: don't write any scope modifier prefix.
+
+  -write        Actually (over)write the generated code to the header and C 
+                source files as assigned to each library through the config 
+                file.
+                Default: don't write.
+
+  -help / -h / -? / --help            Show this help text.
+
+  ...           Additional arguments are added to the file list to scan,
+                assuming '-recurse' was NOT specified on the command line.
