- * TERMCAP
- * The name of the users's termcap file, NOT the termcap entries
- * themselves. This is used ONLY if the program is compiled with
- * CURSES defined (-DCURSES). Even in this case, the program need
- * not find a string for TERMCAP. If it does not, it will use the
- * default termcap file as returned by md_gdtcf();
- * TERM
- * The name of the users's terminal. This is used ONLY if the program
- * is compiled with CURSES defined (-DCURSES). In this case, the string
- * value for TERM must be found, or the routines in curses.c cannot
- * function, and the program will quit.
* ROGUEOPTS
* A string containing the various game options. This need not be
* defined.
*
* If your system does not provide a means of searching for these values,
* you will have to do it yourself. None of the values above really need
- * to be defined except TERM when the program is compiled with CURSES
- * defined. In this case, as a bare minimum, you can check the 'name'
- * parameter, and if it is "TERM" find the terminal name and return that,
- * else return zero. If the program is not compiled with CURSES, you can
- * get by with simply always returning zero. Returning zero indicates
- * that their is no defined value for the given string.
