/*  INSTALLATION: 1) Add following stuff to mud.h
 *
 *  NOTE_DATA *      comments;   (* inside char_data definition *)
 *  DECLARE_DO_FUN( do_comment      );
 *
 *                2) Add do_comment to interp.c, as usual
 *
 *                3) in save.c the following must be added
 *
 * save.c:107:     if ( ch->comments )                                              (* saves comments *)
 * save.c:108:       fwrite_comments( ch, fp );                                           (*  in file *)
 *
 *
 * save.c:411:    ch->comments                        = NULL;                   (* nulls ch->comments *)
 *
 *
 * save.c:457:         else if ( !str_cmp( word, "COMMENT") ) fread_comment(ch, fp ); (*snags #COMMENT*)
 *
 *                4) That looks like it to these eyes.  Lemme know if i forgot anything.
