+Description
+===========
+Structures and functions for simple commandline argument processing,
+option argument handling (short and long forms supported).
+
+Output function for printing out short on-line help for said options
+and program commandline usage.
+
+
+Format for typical commandline:
+
+$ program -a -b -c --long-d -e argument-for-e --long-f="argument for f"
+
+where -a, -b and -c are short options without required arguments;
+--long-d is a long option without argument; -e is short option with
+argument and finally --long-f is long option with argument.
+
+
+Introduction
+============
+Handling of commandline options in th_args_process() has various
+options, which effect how an option is handled. Also the error
+situations (unknown option/no required argument) can be handled
+in different ways.
+
+Typically th_args_process() is called as follows:
+
+BOOL optionHandlerCallback(int optionNumber, char *optionArgument, char *optionName)
+{
+  if (option is OK)
+    return TRUE;
+  else
+    return FALSE;
+}
+
+BOOL nonoptionHandlerCallback(char *argumentString)
+{
+  // return value same as in optionHandlerCallback
+}
+
+
+int main(int argc, char *argv[])
+{
+  if (th_args_process(argc, argv, optList, optListN,
+      optionHandlerCallback, nonoptionHandlerCallback)) {
+    ... arguments OK ...
+  } else {
+    ... arguments invalid or required arguments missing ...
+  }
+}
+
+
+NOTICE!
+-------
+The return value from handler callbacks affects the return value of
+th_args_process(). Additionally, a failure in callback (returns FALSE)
+effects the argument processing if bailOut argument of th_args_process()
+is TRUE!
+
+If bailOut is TRUE, any error/failure in argument processing (including
+callbacks) immediately stops the argument processing and FALSE is
+returned from th_args_process().
+
+If bailOut is FALSE, most errors are "ignored", but FALSE is still returned
+if any errors occured.
+
+
+NOTICE #2!
+----------
+A small temporary buffer of N*sizeof(BOOL) (where N is number of
+options in optList[]) is allocated for processing required options.
+If this allocation fails, the program is immediately exited with
+code 128.
+
+
+Examples
+========
+Example of different options, in a fictional optionlist struct:
+
+optarg_t optList[] = {
+  // Option without arguments
+  { 0, '?', "help",      "Show this help",                    OPT_NONE },
+
+  // Option with a required argument
+  { 1, 'o', "output",    "Output file name",                  OPT_ARGREQ },
+  
+  // Option with optional argument
+  { 2, 'f', "foobar",    "Use foobar, with optional string",  OPT_ARGOPT },
+
+  // This option is required to be given, though without other flags
+  // it may not make much sense.
+  { 4, 'S', "stupid",     "You must give this option",        OPT_REQUIRED },
+
+  // The flags can be combined with OR operator: this option is both
+  // required to be specified, and also requires argument (the filename)
+  { 5, 'i', "input",     "Input file name",                   OPT_REQUIRED | OPT_ARGREQ },
+
+
+  // Option with only long form
+  { 0, 0,   "only-long", "Long option",                       OPT_NONE },
+
+  // Option with only short form
+  { 0, 's', NULL,        "Short option",                      OPT_NONE },
+
+};
+
+const DINT optListN = (sizeof(optList) / sizeof(t_opt));
