Subject: As earlier promised, the index command:

This is a great way to do an inventory on your help system.  I would also
suggest adding a little code to do_help that logs what someone tried to
get help on when they don't succeed in getting anything.

1) I am leaving the interpreter.c stuff up to you
2) Stick this into act.informative.c near do_help
3) just give me a little credit.
* Warning: this uses George's buffer patch. if you don't have it, *
* get rid of the lines with &'s *

ACMD(do_index)
{
   int i;
   int row=0;
   int minlen;
&  char *buf;

   if(!ch->desc)
      return;

   skip_spaces(&argument);

   if(!*argument)
      {
      send_to_char("USAGE: index <letter|phrase>\r\n",ch);
      return;
      }

   minlen=strlen(argument);
&  buf=get_buffer(8192);

   for(i=0;i<top_of_helpt;i++)
      {
      if(!strn_cmp(argument,help_table[i].keyword,minlen))
    {
    row++;
    sprintf(buf+strlen(buf),"|%-23.23s |",help_table[i].keyword);
    if((row%3)==0)
       strcat(buf,"\r\n");
    }

      }
   if(ch->desc)
      page_string(ch->desc,buf,1);
&  release_buffer(buf);
}

stick this into do_help: (yup, use the logf patch)
 if (bot > top)
    {
    send_to_char("There is no help on that word.\r\n", ch);
++  log("HELP: %s Could not find help on %s",GET_NAME(ch),argument);
    return;
    }
