/* ****************************************************************
   The option/-help system has been substantially restructured to
   allow more consistent -h/-help messages.

   There are now two global arrays, opt_def_str g_options (global
   options, parsed in doinit.c), and opt_def_str f_options
   (function-specific options, parsed in initfa.c)

   struct opt_def_str {
     char opt_char;	# getopt single character option letter
     int has_arg;	# does it have an option?
     char *opt_str;	# getopt_long (future) long option name
     char *opt_descr_s;	# short description of option
     char *opt_descr_l; # long description of option (if NULL, use opt_descr_s)
     int opt_rank;	# rank of option (not used)
     int fmt_type;	# fmt type (for defaults): 1,2 ints, 3,4 doubles
     int i_param1;	# int default1
     int i_param2;	
     double d_param1;	# double default1
     double d_param2;
   };

   the g_opt_string and f_opt_string's parsed by getopt() are built
   from these structures, guaranteeing that the options and help
   messages are kept in sync.

   long options descriptions (opt_descr_l) are saved in static arrays
   (e.g. m_opt_descr[] in doinit.c, z_opt_descr[], s_opt_descr[] in
   initfa.c

   The default option values, which are displayed from i_param[1,2],
   d_param[1,2], are set by g_init_opts() and f_init_opts() using
   set_opt_disp_defs().  g_init_opts()/f_init_opts() should be called
   as late as possible in the program.
