+
+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.
